How to Get Rid of Chicken Lice: A Complete Guide to Treatment and Prevention

Parasites such as lice, fleas, and ticks are not merely a cosmetic defect or temporary discomfort. For domestic poultry, especially laying hens and chicks, they pose a real threat to health and well-being. Understanding this danger is the first and most important step toward effective control.

What exactly are parasites dangerous for?

1. Reduced Productivity and Health: Parasites feed on the bird's blood, feathers, and skin. This leads to chronic stress, anemia, and weakened immunity. In laying hens, this directly affects egg production, and in growing young birds, it affects weight gain rate. The bird is constantly in a state of discomfort, which depletes its strength.
2. Disease Carriers: This is perhaps the most serious danger. Parasites can serve as carriers not only for pathogenic microorganisms themselves but also for other pathogens. In the worst-case scenario, an infected bird can become a source of infections dangerous not only to itself but also to humans (zoonoses), including salmonellosis or brucellosis. Therefore, it is important not only to treat but also to prevent further spread of infection.
3. Stress and Deterioration of Well-being: Constant itching, irritation, and fighting parasites cause severe stress in the bird. This can lead to a decline in general well-being and even feather problems (feather plucking).

Are parasites normal?

No. The presence of parasites in moderate numbers may be natural for wild birds, but in the conditions of domestic flock keeping, it is always a sign of a breach of sanitary standards or inadequate care. It is a signal that comprehensive treatment and improvement of housing conditions are necessary.

BLOCK 1: Diagnosis and Fundamentals of Control: What You Need to Know Before Treating

Before reaching for potent medications or folk remedies, it is essential to accurately identify the enemy. Successful eradication of ectoparasites affecting the delicate skin around the birds' ear openings and head begins with correct diagnosis. Mistakes at this stage can lead to a useless waste of time and even the death of the flock from toxic overdose.

In this section, we will cover the basics of recognizing the problem. You will learn exactly which pests cause unbearable itching in laying hens, how to distinguish between lice, ticks, and fleas by their location, and when the line is crossed where home treatment becomes dangerous and requires immediate intervention from a veterinary specialist.

1.1. General Information About Parasites: What Exactly Causes Discomfort in Chickens?

Chicken ears (or, more correctly, parasitic ear infestation) are not a disease in themselves, but a symptom that can be caused by various pathogens. Understanding what exactly causes the discomfort is critical for choosing the correct and safe treatment.

Main Groups of Discomfort Pathogens:

1. Parasites (Lice, Fleas, Ticks): This is the most common cause. Parasites feed on blood, skin sebum, and feathers, causing severe itching, inflammation, and secondary infections. They not only cause discomfort but also weaken the bird's immune system, reducing its productivity and general well-being.
2. Bacterial and Fungal Infections: Due to constant scratching and skin trauma caused by parasites, secondary bacterial or fungal infections (such as pyoderma) can develop in the ears and on the skin. These infections are often masked as simple parasitic infestation but require antiseptic treatment.
3. Hygiene and Environmental Issues: Stagnant puddles, dampness, and poor ventilation in the coop create ideal conditions for the reproduction of not only parasites but also pathogenic microorganisms that can enter the bird's skin and mucous membranes.

How does this affect chickens?

• Itching and Scratching: The main symptom. Hens constantly try to scratch itchy areas, leading to injuries.
• Anemia and Stress: Constant blood-sucking and stress from itching can cause weakness, anemia, and a decrease in general tone.
• Disease Carriers: The most dangerous aspect. Parasites and the affected birds themselves can be carriers of serious infections (salmonellosis, brucellosis, etc.) that are dangerous not only to the bird but also to humans.

Key takeaway for the owner: When 'chicken ears' are detected, one must never limit oneself to folk remedies. Comprehensive diagnosis is necessary to determine whether the main problem is parasitic load or if it is already a secondary infection requiring veterinary intervention. Ignoring the symptoms can lead to chronic health deterioration and reduced immunity for the entire colony.

1.2. Differences Among Parasites (Lice, Fleas, Ticks): What Are They Dangerous For, and Where to Find Them?

For successful parasite control, it is necessary to clearly understand exactly which unwelcome guests you are dealing with. Poultry keepers often confuse symptoms, which can lead to incorrect and ineffective treatment. External parasites, such as lice, fleas, and ticks, although causing severe discomfort, are merely symptoms, not the primary disease. Their presence weakens the hens' immune system, making them more vulnerable to secondary infections.

1. Chicken Lice (Mallophaga):
Lice are perhaps the most common and noticeable parasite. They feed not only on blood but also on feathers, down, and skin sebum. Their colonies can be very dense, especially on young chicks and in areas with poor air exchange. Lice cause severe itching, irritation, and can lead to partial feather loss (malophagy). Their presence is often accompanied by increased feather preening activity with the beak.

2. Chicken Fleas (Sarcoptes and others):
Fleas are small, rapidly reproducing insects. They usually inhabit the litter but can jump onto the bird. Their bites cause severe itching, redness, and can leave small bruises. Like lice, fleas weaken the bird's general condition and can become carriers of bacterial infections.

3. Ticks (Ixodidae and others):
Ticks are more dangerous parasites because they are often carriers of serious diseases (such as borreliosis or ehrlichiosis). They can attach to the skin and feathers, feeding on blood. Their bites can cause not only severe itching but also local inflammations that can become infected with secondary bacterial flora. Ticks require special attention, as their bites can be more serious in terms of health risk.

Comparative Table of Danger and Habitat:

Parasite	Main Food Source	Where Most Often Found	Primary Danger
Lice	Feathers, down, blood	Bird's body, especially in crowded areas	Malophagy, stress, secondary infections
Fleas	Blood	Litter, skin, feathers	Severe itching, weakened immunity
Ticks	Blood	Skin, feathers (especially during outdoor grazing)	Carriers of serious infectious diseases

Key Takeaway: Regardless of the parasite type, their general danger lies in causing chronic stress, depleting the bird's body, and, most importantly, serving as entry points for more dangerous bacterial and fungal infections. Therefore, combating them must be comprehensive, including not only treatment but also improving sanitation in the poultry house.

1.3. When to Call a Veterinarian and Risks of Self-Medication (Safety and Dosage)

Treating birds on your own is standard practice for most poultry keepers, but the line between effective help and mortal danger is very thin. Improper use of even the most popular medications can lead to the death of the flock or render the produce (eggs and meat) unfit for consumption.

When to Call a Veterinarian?

Simple ash baths or standard insecticide treatments will not help if the situation is out of control. Contact a specialist immediately in the following cases:

• Mass Lethargy and Emaciation: If the hens refuse to eat, are huddled up, and their combs and wattles are pale (a sign of severe anemia).
• Deep Skin and Ear Canal Lesions: The appearance of dense gray crusts, pus discharge from the ears or eyes, indicating advanced knemidocoptosis or secondary bacterial infection.
• Neurological Symptoms: Convulsions, loss of coordination, head tilting—these are often signs of severe parasite intoxication or drug overdose.
• Lack of Effect: If the parasite population has not decreased after two consecutive treatments.

Risks of Self-Medication and Safety Rules

The biggest mistake of novice poultry keepers is using medications "by eye" or applying dog and cat products without recalculating the dosage.

Risk of Self-Medication	Consequences for the Bird	Precautions
Insecticide Overdose	Toxic poisoning, paralysis, bird death.	Strictly follow the instructions. Use a syringe for precise dosing of drops.
Ignoring Waiting Periods	Accumulation of toxins in eggs and meat, danger to humans.	Do not consume eggs during treatment and for 10–14 days afterward (depending on the drug).
Mixing Incompatible Agents	Chemical skin burns, increased toxicity of medications.	Never apply organophosphates and pyrethroids simultaneously.

Remember: chickens have a fast metabolism, and toxins penetrate all tissues instantly. Safe parasite control in chickens always begins with accurately weighing several birds to calculate the average drug dose. If you doubt the diagnosis or the dosage, consulting a veterinarian will save both your money and the lives of your layers.

BLOCK 2: Step-by-Step Parasite Eradication Methods (From Lifehacks to Pharmacy)

Moving from theory and risk assessment to decisive action, it is important to understand: eliminating ectoparasites (such as mites, fleas, and lice, often colloquially called "chicken ears") requires a comprehensive approach. A single treatment of the birds is not enough, as the pest population instantly recovers through larvae and eggs hidden in the poultry house.

In this block, we will break down the step-by-step algorithm for complete parasite eradication. We have combined the best practices into three sequential steps: from targeted application of modern veterinary drugs to time-tested ecological folk methods and total disinfection of the coop. This systemic approach will not just temporarily alleviate the birds' suffering but completely eliminate the infection focus without harming the flock's health.

2.1. Medical Approach: Effective Veterinary Drugs (Application, Dosage, Risks)

The medical approach to parasite control is the fastest and often the most reliable way to eliminate severe infestation. However, like any strong chemical intervention, it requires maximum caution and strict adherence to rules. Before using veterinary drugs, it is necessary to accurately determine the type of parasite (lice, fleas, mites) and the degree of infestation, preferably with the help of a veterinarian.

Drug Selection: What and How to Use

Modern veterinary medicine offers a wide arsenal of agents, but the choice must be based on the specific pathogenesis. Drugs are divided into groups: insecticides (kill insects), acaricides (against mites), and antiparasitic complexes.

• For Lice and Fleas: Preparations based on pyrethroids or systemic insecticides are effective. It is important to remember that many agents only act on adult individuals, leaving larvae and eggs, which requires re-treatment at the specified interval.
• For Mites: Specialized acaricides are used. If mites are found, it is necessary not only to treat the birds but also to thoroughly disinfect the entire living space (coop, bedding, feeders).

Critical Application Aspects: Dosage and Risks

1. Strict Adherence to Dosage: This is the golden rule. Drugs are always calculated based on the bird's weight and age. Using too small a dose will allow the parasite population to survive, while an excessive dose will lead to poisoning.
2. Risks of Overdose and Toxicity: Many strong chemical agents can be toxic to birds, especially if they come into contact with mucous membranes (eyes, nose, mouth) or the digestive tract. Application must be done with maximum care, often requiring spraying from a distance to avoid direct contact.
3. Resistance: Due to the frequent use of the same chemical groups, parasites can develop resistance to the drugs. In this case, the veterinarian may prescribe drugs from a different chemical group, which is a key element in comprehensive treatment.

Important: The medical approach should only be part of the overall strategy. It should not replace regular hygiene and prevention described in the following sections. If you doubt the drug or the dosage, it is better to skip the treatment and be safe than to harm the birds.

2.2. Ecological and Folk Remedies: How to Use Ash, Garlic, and Vinegar (Pros, Myths, When Appropriate)

Folk and ecological remedies are an attractive alternative to chemical preparations, especially for novice poultry keepers who fear side effects. However, it is important to understand that these methods most often work as prevention or an auxiliary measure, rather than as the primary treatment for severe infestation. Their main advantage is the minimal risk of toxic poisoning for the hens and humans.

🌿 Ash and Soot: Disinfection and Nutrition

Ash, especially wood ash, possesses natural antiseptic properties. It helps dry out the moist environment in the coop, which is critically important because many parasites and fungi thrive in damp darkness.

• How to use: Mix ash with sand and generously sprinkle it over the bedding. This not only disinfects but also serves as a source of microelements for the chickens.
• Myths and facts: The myth that ash "burns" parasites is exaggerated. In reality, it creates an unfavorable environment for their reproduction and serves as an excellent mineral feed.

🧅 Garlic Infusion: Repellent and Antiseptic

Garlic is a powerful natural remedy. Its essential oils (allicin) have strong antiparasitic and antifungal properties.

• How to use: Pour water over crushed garlic and let it steep. Use this solution to spray the coop (not directly on the birds to avoid irritation) or add it to the drinking water as a preventive measure.
• When suitable: Ideal for prevention and maintaining cleanliness, as well as for combating unpleasant odors in the enclosure.

🍶 Vinegar and Marinades: Surface Disinfection

Vinegar (especially apple cider vinegar) is an excellent, safe disinfectant for surfaces. It kills many bacteria and mold that can contribute to secondary infections after parasite bites.

• How to use: Dilute vinegar with water in a 1:5 ratio and use it to wipe down the floor, walls, and waterers in the coop. Important: Do not spray concentrated vinegar on the chickens' feathers, as it can cause severe irritation and dryness.
• Pros: Ecological, accessible, effective against bacterial contamination.

⚠️ When Folk Remedies Are Ineffective?

Folk remedies are excellent for maintaining hygiene and prevention, but they cannot replace veterinary drugs if the infection has reached epidemic stages or if the parasites are resistant to simple remedies. In cases of severe infestation (feather loss, anemia, sharp decrease in activity), a medical approach, as described in the previous section, must be used.

2.3. Professional Disinfection: Complete Treatment of the Coop and Its Surroundings (Cleaning, Treatment, Precautions)

Even the most effective drugs for treating the birds themselves will be useless if the coop is not thoroughly disinfected against parasites in a timely manner. Most ticks, lice, and fleas spend only part of their time on the host's body, hiding in wall crevices, under roosts, and in the bedding. Complete sanitation of the enclosure is the only way to break the pest reproduction cycle and ensure proper coop care.

Stage 1: Mechanical Cleaning and Preparation

Before starting chemical treatments, the poultry house must be completely prepared:

• Bird Evacuation: Move all chickens to a temporary pen. Treating in the presence of birds is strictly forbidden.
• Bedding Removal: Completely remove old straw, sawdust, and nesting material. This mass must be burned or disposed of far from the site, as it is literally teeming with parasite eggs and larvae.
• Dry and Wet Cleaning: Thoroughly scrape manure from walls, roosts, and floors. Wash all wooden and concrete surfaces with hot water mixed with calcium carbonate.

Stage 2: Selection of Agents and Disinfection

To ensure successful parasite control in chickens, powerful chemical solutions are used to treat the empty enclosure:

• Insecticide/Acaricide Solutions: Preparations based on deltamethrin (e.g., "Butox" or "Delcid") are diluted according to instructions and sprayed generously over all surfaces. Special attention should be paid to the joints of wooden structures, crevices, and nests.
• Carbofos: A time-tested agent for treating floors and walls, destroying even resistant populations of ticks.
• Sulfur Pellets: Used only in sealed enclosures. The released gas penetrates the smallest crevices, but remember that sulfur dioxide causes severe corrosion of the coop's metal elements.

Stage 3: Safety Measures and Completion of Work

Eliminating parasites from birds requires strict adherence to personal and veterinary safety rules:

1. Human Protection: Always work in a respirator, safety goggles, rubber gloves, and protective clothing.
2. Exposure and Ventilation: After spraying or burning pellets, close the coop for a period of 2 to 12 hours (according to the drug instructions). Then, ensure cross-ventilation for a minimum of 24–48 hours.
3. Reintroduction: Ensure that the chemical odor has completely disappeared. Lay down fresh, dry bedding, install clean feeders, and only then return the flock.

BLOCK 3: Prevention and Long-Term Care: How to Prevent Re-infestation

After we have covered acute treatment methods and performed professional disinfection, it is important to understand that eliminating parasites is not a one-time event. Parasites and diseases can return if a preventive regime is not maintained. Therefore, the most important stage in fighting fleas and ticks is establishing sustainable care habits for both the birds themselves and their housing. Proper care and maintaining sanitary conditions not only prevent re-infestation but also strengthen your chickens' immune systems, making them healthier and more productive.

This block is dedicated to a long-term strategy. We will look at how to maintain ideal hygiene in the coop, how to properly organize free-range access, and what seasonal precautions must be observed throughout the year. Only a comprehensive approach guarantees that your chickens will remain healthy and free from unwanted guests.

3.1. Hygiene and Bird Care: Basic Rules for Keeping Chickens to Avoid Problems

Maintaining the health of the chickens and preventing re-infestation is a comprehensive process that begins with daily routine and the correct attitude toward the environment. A passive approach to care often leads to chronic problems, so it is important to implement systematic preventive measures.

🐔 Hygiene and Care of the Birds Themselves

The bird itself is a carrier and a source of infection. Therefore, care must be aimed not only at treatment but also at strengthening the immune system.

• Regular Inspection: Examine the feathers and skin of the chickens daily. Pay attention to unusual spots, feather loss, redness, or areas where parasites might hide. This allows you to detect the problem at the earliest stage, when treatment will be most effective.
• Proper Nutrition: Ensure a balanced diet. Healthy nutrition with sufficient vitamins (especially B group) and minerals strengthens the immune system, making the birds more resistant to stress and infections.
• Stress Control: Avoid sudden temperature changes and drafts. Overcrowding or constant noise can weaken the immune system, making the chickens more vulnerable to parasites.
• Socialization: If possible, keep the chickens in a group. Group housing promotes natural observation and mutual support, which is important for psychological comfort.

🏡 Coop and Pasture Sanitation: Preventing Infestations

The coop and surrounding area are not just a place to sleep, but part of the life support system. Their cleanliness directly affects the health of the birds.

• Litter is Key to Success: The litter must be dry, clean, and regularly replaced. A mixture of sawdust and straw is ideal. It should absorb moisture and prevent the development of mold and bacteria. Remove wet and soiled material daily.
• Manure Removal: Manure must be removed at least twice a day. This is not only a hygienic but also a preventive measure, as pathogenic bacteria and parasite larvae can develop in fresh manure.
• Limiting Contact: Strictly exclude contact between the chickens and wild animals (wild birds, stray cats, dogs). Wild animals can bring new types of parasites and disease pathogens that domestic poultry are not immune to.
• Fencing the Pasture Area: Be sure to fence the area with netting. This not only protects the chickens from predators but also allows you to control their habitat zone, minimizing contact with potentially contaminated external environments.

🗓️ Seasonal Prevention: Annual Care Calendar

Prevention must be cyclical and take into account seasonal changes. This allows you not only to eliminate the current problem but also to prepare the birds for future challenges.

• Spring (Active Growth Period): Pay special attention to strengthening the immune system. Increase the amount of vitamin and mineral supplements in the diet. Conduct a primary cleaning of the coop after the winter period to destroy accumulated spores and eggs.
• Summer (Peak Activity and Parasites): This is the most dangerous period. In addition to regular treatment, it is necessary to intensify control over cleanliness. In hot weather, increased humidity and heat promote the reproduction of fleas and ticks. Regularly inspect the birds and use preventive treatments as recommended by a veterinarian.
• Autumn (Preparation for Dormancy): Gradually reduce the load on the birds. Ensure that feed supplies and coop cleanliness are perfect. Conduct a final treatment of the premises to prepare them for harsher conditions.
• Winter (Minimal Activity): Maintaining warmth and dryness is critical. Ensure the chickens have constant access to clean, dry litter and a place protected from drafts. Minimize outdoor access to avoid contact with winter parasites and cold.

3.2. Coop and Pasture Sanitation: Rules for Disinfection, Litter, and Isolation

Maintaining cleanliness and sterility in chicken housing is not just a recommendation, but a key element of preventing parasitic and infectious diseases. Parasites and diseases are often transmitted through the contaminated environment, so the sanitary regime must be strict and regular.

1. Litter Care: The Basis of Hygiene

The litter (straw, sawdust, hay) must perform several functions: absorb moisture, retain heat, and, most importantly, serve as a barrier against pathogens. However, it is also an ideal environment for the reproduction of bacteria and parasite larvae.

• Regular Replacement: The litter must be changed no less than once every 1-2 weeks, depending on humidity and the number of birds. More often during periods of high humidity or when the chickens are sick.
• Correct Composition: It is ideal to use dry, clean materials (e.g., fresh, dry sawdust or hay). Avoid wet or dirty litter, as it promotes the development of mold and unpleasant odors.
• Manure Removal: Manure must be removed daily. Do not allow it to accumulate, as it is a source of many bacteria and parasite eggs.

2. Coop Disinfection: Fighting the 'Invisible'

Disinfection should be carried out not only after treatment but also regularly for preventive purposes, especially during the off-season or when the weather deteriorates. The goal is to destroy eggs, larvae, and spores that can survive on surfaces.

• Surface Treatment: The floor, walls, and shelves must be regularly treated with disinfectants. Solutions containing chlorine-based preparations are effective (while observing dosage and safety for the birds) or specialized veterinary disinfectants.
• Equipment Treatment: Waterers and feeders also require thorough cleaning and disinfection to prevent the accumulation of bacteria and to avoid becoming a source of infection.
• Ventilation: Ensure maximum air circulation. Good ventilation not only prevents moisture buildup but also reduces the concentration of pathogenic microorganisms in the air.

3. Isolation and Pasture: Environmental Control

Contact with the external environment and other animals is the main source of infection. Therefore, isolation rules must be strictly followed.

• Territory Fencing: The pasture area must be clearly delimited and preferably fenced with netting. This prevents contact with wild animals (rodents, wild birds) that can be carriers of fleas and ticks.
• Access Control: Do not allow unauthorized animals (cats, dogs) free access to the coop unless they have been thoroughly treated. These animals can bring parasites with them.
• Waste Cleanup: The surrounding area must be clean. Regularly remove feed remnants and manure to minimize the area's attractiveness to pests.

Remember: A comprehensive approach is a combination of cleanliness, proper nutrition, and timely treatment. Only this regime guarantees that you have not just gotten rid of parasites, but also prevented their return.

3.3. Seasonal Prevention: How and How Often to Treat Birds and Housing Throughout the Year

Seasonal changes directly affect the life cycle and activity of ectoparasites. To prevent mass infestation of the birds, preventive measures must be systematic and adapted to the specific time of year.

Calendar of Seasonal Parasite Control Work

• Spring (Awakening Period): As the air temperature rises above +10 °C, mites, fleas, and feather lice emerge from a state of anabiosis. During this period, the first general cleaning of the coop must be performed: completely replace the litter, wash the perches, and whitewash the walls with freshly slaked lime. The birds must be inspected very carefully, and the ash-sand bathing areas in the pasture must be refreshed.
• Summer (Peak Activity): In hot weather, parasites multiply exponentially. The flock should be inspected every 10–14 days. It is recommended to regularly sprinkle dry, strongly scented herbs (wormwood, plantain, lavender) in the nests and on the litter. A preventive treatment of the coop with mild insecticides should be carried out once a month.
• Autumn (Preparation for Winter): The seasonal molting period weakens the hens' immune system, making them vulnerable. Before stable cold weather sets in, a second general disinfection of the premises should be performed (for example, using sulfur powder or approved veterinary solutions). The birds should be treated with drops on the nape or with insecticide powder.
• Winter (Control Period): Due to crowded conditions in an enclosed space and high humidity, the risk of lice spread increases. Wet treatments of the birds are prohibited in winter to avoid hypothermia. Dry methods are used for prevention: dusting feathers with diatomaceous earth or clean wood ash.

Treatment Schedule and Methods Throughout the Year

Frequency	Treatment Object	Recommended Method and Agents
Weekly	Nests and litter	Visual check for dryness, localized dusting with diatomaceous earth
Monthly	Birds (selective)	Inspection of plumage under wings, in the cloaca area, and on the neck
Quarterly	Equipment and perches	Cleaning and treatment with disinfectants
Twice a year	Entire poultry house	General disinfection, wall whitewashing, complete replacement of litter layer

Summary: Key Stages of Parasite Eradication in Hens and FAQs

Combating parasites in hens is not a one-time event but a comprehensive, cyclical process that requires attention at every stage. To achieve sustainable results and prevent re-infection, three key principles must be remembered: diagnosis, treatment, and prevention.

1. Diagnosis: Do not panic and act systematically.

Before applying any agents (whether veterinary drugs, ash, or garlic infusion), it is necessary to accurately determine the type and scale of the problem. Inspect the birds and the coop: lice, fleas, mites—each parasite requires its own approach. If you doubt the diagnosis or see signs of severe bird weakness, always start by consulting a veterinarian. Self-medication can be ineffective or, worse, toxic.

2. Treatment: A comprehensive approach is the key to success.

Effective parasite eradication requires simultaneous treatment of three areas: the birds themselves, the coop, and the pasture area. It is not enough just to treat the hens. Parasites can hide in the litter, on the walls, and in the feathers, waiting for re-infection.

• Priority — Hygiene: Start with a complete cleaning and disinfection of the coop (replacing litter, treating surfaces). This will deprive parasites of breeding grounds.
• Agent Selection: Use methods appropriate to the degree of infestation and the condition of the birds. Veterinary drugs may be required for severe outbreaks, but ecological agents (such as ash or herbal infusions) are excellent for prevention and mild cases.

3. Prevention: The best defense is preventive measures.

The most important stage. Even after successful treatment, if the housing conditions are not changed, the infection will return. The main preventive measures include:

• Strict sanitary regime: Daily cleaning of droppings and food scraps. Regular litter replacement.
• Isolation: Minimizing contact with wild birds and animals.
• Treatment Schedule: Adhering to the seasonal schedule for treating the coop and the birds to maintain immunity and environmental cleanliness.

Remember: Success in fighting parasites is not only about chemical agents but also about discipline in caring for the coop. Only a comprehensive approach guarantees the health and productivity of your flock.
