Coccidiosis, a common and potentially devastating disease in chickens, is caused by single-cell parasites known as coccidia. As poultry keepers, understanding the impact of this disease and implementing preventive measures is paramount for maintaining the health and productivity of our flocks.
In this article, we will explore Coccidiosis, covering its causes, symptoms, and the best prevention and treatment strategies to ensure the well-being of our feathered companions.

Understanding Coccidiosis in Chickens
Coccidiosis is a highly contagious disease caused by various species of coccidia. These microscopic parasites invade the intestinal lining of chickens. They have a complex life cycle, with oocysts (think parasite eggs/offspring) present in the environment through the droppings of infected birds. When healthy chickens come into contact with contaminated areas, they inadvertently ingest the oocysts, which can lead to infection.
According to this article from Penn State, the ingestion of a few oocysts is not a problem. Problems arise when there is an overgrowth of the parasites. Therefore, continuous use of medicated feed or medication is not necessary for healthy flocks. Also, limiting unnecessary treatment helps to prevent drug-resistant strains of coccidia from developing.
Symptoms
Common signs of Coccidiosis in chickens include diarrhea, lethargy, reduced appetite, weight loss, pale skin, head and neck drawn into body, and ruffled feathers.
If your chicken’s dropping contains blood or orangish mucus, then you might be dealing with Coccidiosis. (Please click on the Penn State link above for examples of infected fecal matter.) If your chickens have diarrhea, don’t panic there are other causes of diarrhea and remedies for it.
If you are wanting to check for pale skin, it is most easily seen in combs and wattles of a sick bird.

If left untreated, Coccidiosis can lead to severe dehydration and even mortality, posing a significant threat to flocks of all sizes.

Causes and Risk Factors
Coccidia thrive in warm, humid environments, making poultry houses and coops susceptible to contamination. Factors such as overcrowding, poor ventilation, and inadequate sanitation can facilitate the spread of coccidia.
Additionally, introducing new birds to an existing flock without proper quarantine measures increases the risk of coccidiosis transmission.
However, even if you are doing everything correctly, your chickens may still come into contact with the droppings of infected birds. I say this to remind you that you are taking wonderful care of your flock (you are reading this, after all!). Coccidiosis sometimes just happens, and there are treatments for it. Keep loving on those beautiful flocks, and don’t worry over what-ifs!
Prevention of Coccidiosis in Chickens
The foundation of coccidiosis prevention lies in strict biosecurity measures. When introducing new birds, isolate them for at least two weeks to monitor their health and prevent potential disease transmission. Regularly clean and disinfect coops, feeders, and waterers to minimize the risk of contamination. Restricting visitor access and using footbaths can further prevent the accidental spread of coccidia.
Effective flock management is also crucial. Sufficient space and ventilation in poultry housing help reduce stress and disease transmission.
Balanced nutrition, including a diet rich in essential nutrients and access to clean water, strengthens the chickens’ immune systems.
Consider natural alternatives, such as herbs and probiotics, to bolster immunity against Coccidiosis.
Early Detection and Diagnosis
Regular health checks are pivotal in identifying the early signs of Coccidiosis. You can perform these checks yourself by observing your chickens. Vigilance is key to noticing changes in behavior, appearance, or droppings.
If you suspect Coccidiosis, consult a veterinarian promptly for a thorough diagnosis. Early intervention is important to prevent the disease from spreading throughout the flock.
Treating Coccidiosis in Chickens
Timely and appropriate treatment is essential if Coccidiosis is confirmed. Veterinarians often prescribe coccidiostats (also know as anticoccidial medications), which are effective in controlling the parasite population.
Adhere to the recommended treatment cycle and withdrawal periods before consuming eggs or meat from treated birds. In other words, check the labels of any medication or supplement and follow all of the directions.
PoultryDMV has a wonderful chart with recommendations for treatments and tips. For example, they mention that vitamin B can interfere with the efficacy of anticoccidial medications.
Natural Remedies and Supportive Care
For those seeking natural alternatives, herbal supplements, essential oils, and probiotics can aid in strengthening the chickens’ immune systems and supporting their recovery. Always double or triple-check their safety for chickens when using herbs or essential oils! And follow directions carefully.
Creating a stress-free environment with proper bedding, shelter, and nutrition enhances their ability to fight off infections.
Long-Term Management Strategies
Coccidiosis prevention requires a comprehensive, long-term approach. Implement rotational grazing and pasture management to prevent the buildup of coccidia in the environment. Continuously adapt management practices based on past outbreaks and experiences to minimize the risk of future infections.
A droppings pit or board under chicken perches are great ways to separate chickens from their droppings further. It can be as simple as a board or tray that slides under the perches that you can easily pull out and clean.
Conclusion
Coccidiosis is a significant concern for chicken keepers. However, it can be managed effectively armed with knowledge and a proactive approach. By adhering to biosecurity practices, providing optimal care, and seeking veterinary guidance, when necessary, we can safeguard the health and happiness of our cherished chickens, ensuring they thrive in our farms and homesteads.
Have you struggled with Coccidiosis in your flock? Let me know in the comments! I hope that you and your flocks are well and thriving!
My chickens have had coccidia in the past for which the veterinarian prescribed Amprolium, a vitamin B blocker, for treatment. Currently I am raising chicks (separately in a brooder) who are now almost 5-weeks old. I had hoped to purchase starter feed, but the store did not have it in stock. I’ve been concerned about one or two of the chicks who seem to have quite liquid poops, but collecting it for analysis is a challenge as when and where they defecate is anyone’s guess. Should I be concerned?
