Coccidiosis and Chicken Poop: Understanding the Connection
Coccidiosis is a poultry disease caused by a protozoa parasite that is often found in the environment where chickens and chicks are raised. This parasite can affect both healthy and infected birds, leading to damage in the intestines. The lining of the chicken’s intestines becomes damaged, causing malnutrition and potentially leading to an irreparable condition that may result in death.
The immune system of the chickens plays a critical role in managing the small population of coccidia, which is naturally present in their gut. However, if their immunity is compromised, infection sets in, and the ongoing issue of coccidiosis can worsen. Early diagnosis of the symptoms is key to managing this ailment, as untreated infection can lead to severe damage to the intestines.
The exposure to the parasite is especially harmful to young chicks, who haven’t built up sufficient immunity. This can lead to rapid spread within the flock, affecting more birds and making the situation harder to control. Without proper care, the damage caused by coccidiosis can turn into a serious disease that threatens the health of the entire flock.
The Culprit: Coccidia Parasites
The coccidia parasite is the primary cause of coccidiosis in chickens. These microscopic protozoa, mainly Eimeria species, live in the intestinal tract of chickens and infect different areas, causing severe damage.
The coccidia parasite has many species-specific types, such as E. acervulina, E. maxima, and E. tenella, each infecting specific parts of the chicken’s intestines. While some species are common and affect chicks, others are more uncommon but still cause significant health issues as chickens grow.
Coccidia parasites spread rapidly in the environment. Oocysts, which are the fertilized egg cysts of the coccidia parasite, are released in the chicken’s poop and can survive in soil, litter, feed, and water.
These oocysts are noninfective at first but sporulate when exposed to a moist and warm environment, usually in temperatures ranging from 70°F to 90°F. Once they become infective, the oocysts can persist in the environment for months, and the infection cycle continues as chickens ingest the contaminated feed or water, or even peck at the ground.
After ingestion, the oocysts are crushed by the chicken’s gizzard, releasing zoites that invade the intestinal tract. These zoites then proliferate, reproduce, and eventually develop into new protozoa, continuing the protozoan life cycle.
This continuous cycle of infection can lead to severe health problems in chickens, including damage to their intestines, malnutrition, and, in extreme cases, death if not properly managed.
How Does Coccidiosis Affect Your Chickens?
Coccidiosis is a common infection caused by the coccidia parasite that affects chickens. The parasite enters the chicken’s body when they consume oocysts present in the environment. These oocysts cause damage to the intestines, leading to poor growth rates and affecting production.
The infection can also weaken the immune system, making chickens more susceptible to other secondary infections. Young chickens, especially those between three to six weeks of age, are at a higher risk as their immunity is still developing.
Infected chickens with a compromised immune system, or those under stress, are more likely to suffer from chronic diseases, like Marek’s disease, which can make them more vulnerable to coccidiosis. Adult chickens, although less likely to get infected if they have built up immunity, can still be affected by different species of coccidia.
A strong immune system developed through ingesting small amounts of oocysts helps chicks build active immunity during their first few weeks, preventing major outbreaks of coccidiosis in the future.
Recognizing Symptoms of Coccidiosis in Chickens
When chickens are infected with coccidiosis, they often show several symptoms that can help you identify the disease early. One of the most common signs is diarrhea, which may appear bloody, watery, or whitish depending on the species of coccidia involved, such as E. acervulina. Infected chicks and chickens will also show signs of lethargy and a poor appetite. They may lose interest in eating and drink less, leading to dehydration and malnutrition.
As the disease progresses, ruffled feathers and huddling are common symptoms due to weakness from malnutrition. You might notice that the chicken’s comb and wattles become pale, shriveled, or shrunken, which indicates discomfort.
In younger chickens, you might see slow growth or numerous deaths, while mature chickens may experience weight loss, a decrease in egg production, and a loss of pigment in their skin and shanks. These symptoms can be age-specific, affecting chicks and mature chickens in different ways.
Key Symptoms and Clinical Signs of Coccidiosis in Chickens
Coccidiosis causes several clinical signs in chickens, with diarrhea being one of the most common and noticeable symptoms. The diarrhea can range from watery to bloody, and sometimes even whitish, depending on the type of protozoa causing the infection, such as E. acervulina.
Along with diarrhea, chickens may show signs of lethargy, poor appetite, and a lack of interest in eating or drinking, leading to dehydration and malnutrition. Weakness, ruffled feathers, and huddling together are also key signs, as chickens feel uncomfortable and often try to isolate themselves from the rest of the flock.
Symptoms can vary depending on the age of the chicken. Chicks typically show signs like slow growth, severe diarrhea, and in extreme cases, numerous deaths. In mature chickens, you may notice slow egg production or even no egg production, alongside a loss of pigment in their skin and shanks.
Weight loss and pale or shrunken comb and wattles are also visible signs. Lesions in the intestine are common, and the severity of these lesions depends on the species of Eimeria involved. Diagnosing the infection often requires diagnostic data related to the location and aspect of the lesions.
Diagnosing Coccidiosis: Confirming the Culprit
When you suspect coccidiosis in your chickens, it’s crucial to confirm the infection through a proper diagnosis. The symptoms of coccidiosis can vary, with acute cases causing severe symptoms like bloody diarrhea and rapid death. In contrast, chronic cases may present with milder symptoms, such as failure to thrive, grow, or reproduce.
Identifying the level of infection is key, and understanding the species of coccidia causing the infection can help guide treatment. The immune system of your flock plays a role in how severe the infection becomes, with some chickens being more susceptible than others.
A fecal float test is a common method for diagnosing coccidiosis. This test involves collecting a feces sample from the infected bird or birds in your flock or brood. The sample is then mixed with a liquid that has a specific gravity greater than the coccidia eggs, which helps separate and concentrate the parasite eggs.
This test can reveal the presence of oocysts, the eggs of protozoa, which are the main cause of coccidiosis. Once oocysts are identified, the veterinarian can confirm whether your chickens are shedding coccidia and identify the species causing the infection.
What Causes Coccidiosis in Chickens?
Coccidiosis is caused by the coccidia parasite that affects the digestive tract of chickens. Healthy adult chickens can tolerate small numbers of coccidia without any health issues, but unfamiliar strains or high levels of coccidia can lead to severe illness and even death.
The parasite spreads through faeces, where oocysts are passed out by infected birds. These eggs are then ingested by other chickens, starting the life cycle again when they hatch in the intestine, invade the gut lining, and impair digestive function as they multiply.
The infection spreads quickly within a flock, especially in wet conditions where oocysts can survive and thrive. Environmental changes, unsanitary, or overcrowded conditions in the backyard can also increase exposure to the parasite, leading to higher parasite loads. Chickens experiencing stress or malnutrition are more susceptible to coccidiosis.
Introducing new birds into your flock without proper biosecurity can also bring in new strains of the coccidia parasite, making it essential to practice good biosecurity. Regularly disinfecting equipment, including preowned feeders and egg cartons, is a good habit that should become second nature.
The protozoan genus Eimeria, which causes coccidiosis, is an intracellular parasite that has a complex life cycle, involving both asexual and sexual stages. The parasite feeds off the chicken’s intestines, which can lead to necrotic enteritis, making it harder for the chicken to absorb nutrients.
The mature oocysts produced by Eimeria are passed through the faeces, where they can be carried by mechanical carriers like insects or wild birds, but they do not serve as a biological reservoir. To ensure proper control, it’s important to sporulate the oocysts under ideal environmental conditions, ensuring they are released into the lumen of the intestine to sporulate again and complete the life cycle.
Treating Coccidiosis in Chickens
When dealing with coccidiosis, it’s essential to isolate infected birds from the rest of your flock to prevent the infection from spreading. Early treatment is key, as severe cases can lead to intestinal damage, diarrhea, and dehydration. Medicating your chickens with prescribed anticoccidial drugs will help control the parasite and reduce secondary infections.
Veterinarian care should be sought to ensure proper treatment and management, especially for sick chickens. Regular cleaning of the brooder or pasture where the chickens are housed can help prevent contamination from oocysts and reduce the risk of reinfection.
In addition to medicating, offering medicated feed can provide protection and help build immunity in your chicks. This coccidiostat medication can aid in preventing the spread of coccidiosis while supporting the chicks’ ability to resist the parasite. It is important to administer the feed for up to 8 weeks, as it prevents the infection from becoming fatal.
However, good management of your flock is just as crucial. Ensuring a nutritious diet, providing probiotics to improve gut health, and practicing biosecurity by disinfecting tools and quarantining new birds will also help maintain a healthy flock.
Additionally, apple cider vinegar in the drinking water has been shown to help reduce exposure to oocysts, especially when wild birds are present. Keeping the coop clean, dry, and avoiding overcrowding is critical in preventing the spread of coccidiosis.
Exposure to sunlight, sub-zero temperatures, and dry conditions can also kill oocysts, minimizing the risk of outbreaks. With these steps, your chickens can stay healthy, productive, and free from coccidiosis.
Prevention and Control of Coccidiosis in Chickens
Practice Good Bio-Security
To keep your chickens safe, it’s essential to practice good biosecurity. Avoid wearing the same clothing or shoes and using the same tools or equipment that were exposed to other farms or activities.
This helps prevent the introduction of new strains of coccidia to your flock, which they may not have immunity against. Additionally, it protects your neighbor’s chickens from getting infected with diseases present on your farm.
Sanitize the Coop & Brooder
Regularly sanitize your coop and brooder to prevent the spread of coccidia. Daily cleaning of the litter and ensuring it stays dry can significantly reduce the risk of oocysts surviving and infecting the chickens. Use composting methods, such as flake wood shavings or straw, to help destroy coccidia eggs. A well-ventilated coop can also help keep the environment clean and reduce the spread of parasites.
Keep Feeding Areas Clean & Dry
Ensure that feeding areas are kept clean and dry to avoid contamination of the food and water. Soiled or damp bedding can create a breeding ground for coccidia and other infections. Avoid throwing food on the ground, as it can become contaminated with droppings or oocysts. Clean feeders and dishes regularly to maintain a healthy environment for your chickens.
Provide Clean, Fresh Water
Clean, fresh water is essential to prevent coccidia from contaminating your flock. Use nipple waterers to provide contained water and avoid the risk of contamination that can occur with open water sources. Chickens, especially chicks, will quickly adapt to drinking from nipple waterers, and it has been proven to help reduce disease spread, as seen in commercial chicken farms.
Keep Brooders and Coops Clean & Dry
A clean and dry environment is vital for preventing the spread of coccidiosis. Regularly clean and change bedding in the brooder and coop to prevent the buildup of oocysts. Damp bedding can create the perfect conditions for parasites to thrive. Ensuring that the space remains dry and well-maintained is key to managing outbreaks.
Provide Adequate Space
Overcrowding can increase the risk of coccidiosis outbreaks, as parasites spread more easily in cramped conditions. Make sure each chicken has at least 4 square feet of space inside the coop, 10 square feet in the chicken run, and 6 square feet of flooring in the brooder. Proper space allows for good ventilation and reduces stress, which can make chickens more susceptible to infections.
Promote Natural Immunity in New Chicks
Introducing new chicks to a properly maintained chicken yard helps them build a natural immunity to coccidiosis strains present in your flock. Start by gradually allowing them to explore their environment by the time they are about 4 weeks old. This controlled exposure will help them develop immunity and prepare them for future exposure to coccidia.
Vaccination
Vaccination is an effective way to prevent coccidiosis in chickens, especially in commercially purchased chicks. However, always confirm with the supplier that the chicks are vaccinated before introducing them to your flock. Remember that vaccinated chicks should not be fed medicated feed, as it can nullify the protective effects of both treatments.

Good Management Practices
Outdoor Exposure
Allowing chicks to have access to the outdoors is one of the best ways to help them build immunity to coccidia in their natural environment. Raising free-range or pasture-raised chicks exposes them to gradual exposure to oocysts, which helps them develop resistance to coccidiosis.
Warm, sunny days are ideal for this, as chicks can peck around in the grass and dirt, which naturally helps reduce the concentration of the parasite in the flock. Allowing them to roam freely in these conditions ensures they are not confined to limited areas that can lead to overcrowding and increased exposure to high levels of coccidia.
Improving Hygiene
Hygiene is a crucial factor in preventing coccidiosis. To keep your flock healthy, make sure to keep the chicken coop and brooder clean. Dirty litter and chicken poop can easily contaminate feed and water sources, which then spreads oocysts throughout the flock. Regularly refresh the water and remove spills to avoid moistening the litter, as this creates an ideal breeding ground for parasites.
Use hanging feed systems to prevent dirt and poop from being kicked into the feed, ensuring the feed remains clean and reduces the risk of contamination. By keeping your flock’s environment clean, you can significantly lower the chances of coccidiosis spreading.
Immunity and Prevention in Chicks
To prevent coccidiosis in chicks, it’s important to focus on building their immunity from an early age. Immunity develops when chicks are gradually exposed to Eimeria parasites like E. maxima and E. brunetti in a controlled environment.
This helps the chicks build cross-protection against various strains of the coccidia parasite. While natural exposure is important, live vaccines can also play a role in boosting the chicks’ ability to fight off the infection, especially when the disease is prevalent in the environment.
How Immunity Develops in Chickens
Immunity in chickens is species-specific and typically develops as the chicks encounter coccidia in their surroundings. As the chicks get exposed to small amounts of the parasite, their immune systems adapt, and they become more resistant to future infections. Over time, the immune system strengthens, allowing the chickens to fight off coccidiosis with less severity.
Cross-protection between different strains of Eimeria can occur, but it’s often partial, meaning that chicks can be susceptible to different types of coccidia if they haven’t been exposed to them before.
Importance of Probiotic Supplements
Probiotic supplements are vital for maintaining a healthy gut environment in chicks. These supplements promote competitive exclusion, a process where beneficial bacteria in the gut outcompete harmful bacteria, thereby improving overall gut health.
Adding probiotics to the chicks’ water can help reduce the chances of infection by coccidia and other harmful organisms. By supporting the gut, probiotics also enhance the chicks’ ability to absorb nutrients, contributing to their growth and productivity over time.
Frequently Asked Questions
How do you treat coccidia in chickens?
Luckily, coccidiosis can be treated successfully if detected early. To control an outbreak, it’s crucial to treat all the birds in the flock. The most commonly used treatment for coccidiosis is Amprolium, which works by preventing the parasite from absorbing nutrients and multiplying.
What does coccidiosis chicken poop look like?
Coccidiosis-infected poop usually appears mustard yellow or brown with a foamy texture, and it can sometimes become very bloody. I also notice that my chickens develop messy or soiled butt feathers when the infection begins.
Can chickens recover from coccidiosis on their own?
If possible, move the healthy chickens to a separate run or pasture to avoid contaminated droppings. Coccidiosis is self-limiting, so infected chickens can recover in a few weeks, with or without treatment.
Is coccidiosis painful for chickens?
This causes pain for the birds, leading them to stop eating and adopt a hunched posture with ruffled feathers. The damage to the gut wall impairs nutrient absorption, resulting in weight loss and diarrhoea.
conclusion:
coccidiosis is a serious poultry disease caused by the coccidia parasite, affecting the digestive tract of chickens, especially young animals with underdeveloped immunity. Early detection and proper management practices, such as isolation, using medicated feed, and maintaining good biosecurity, are crucial to controlling outbreaks and preventing intense infections.
By allowing chicks gradual outdoor exposure to build natural immunity and using probiotic supplements, you can significantly reduce the risk of coccidiosis spreading within your flock. Keeping the coop clean, dry, and well-ventilated, along with ensuring adequate space, helps prevent overcrowding and the buildup of oocysts, reducing the chances of reinfection and ensuring your chickens stay healthy and productive for years.
