How to Prevent Coccidiosis in Your Chicken Flock

Among the many diseases and health issues chickens can face is coccidiosis, a parasite that targets chicks. Coccidiosis is one of the top reasons behind chick deaths. It can be devastating to your new flock if you’re not careful. There are treatment options for this parasite, but it can still do a lot of damage if you don’t catch early enough. As with many chicken diseases, the best treatment is prevention. Learn how to prevent coccidiosis in your chicken flock with this overview.

How to Prevent Coccidiosis in Your Chicken Flock


Before you set out to protect your chickens from coccidiosis, it’s important to know what you’re getting into. Unlike the viruses and bacteria of other common chicken diseases, coccidiosis comes from an intestinal parasite. Coccidia parasites will infiltrate and spread through the cells that line the chicken’s gut wall. Once inside a cell, the parasites will multiply until that cell bursts. Afterward, they will spread to a new cell and start the process over. The presence of coccidia parasites damages a chicken’s gut, impairing the digestive system and damaging the bird’s ability to absorb nutrients from food. As such, weight loss and a lack of appetite are two common symptoms of this disease. Other symptoms include lethargy, pale combs and skin, and bloody or foamy droppings.


Chicks and chickens catch coccidiosis by accidentally ingesting the parasites, often through infected soil or droppings from another bird. Contaminated soil or droppings can get into your flock’s food or water supply, making it easy for the disease to make its way through your flock. Once a colony of coccidia parasites establishes itself within a chicken, it will begin to produce microscopic eggs called oocysts that leave the bird through its droppings, allowing the cycle to continue.


Coccidiosis primarily spreads through contaminated food and water supply, making coop cleanliness a key prevention method. Make sure your flock always has dry bedding. You should also keep food and water supplies off the ground and do your best to prevent or quickly clean up spills. This will prevent your chickens from eating off the floor, lowering their risk of ingesting contaminated food. Remember that chicks are the most vulnerable to coccidiosis, so it’s a good idea to get your newest flock members vaccinated.
