    Coccidiosis And How To Treat It

    What Is Coccidiosis

    Coccidiosis is a disease that poultry can get from a certain parasite, called a Coccidia. They are ingested through the mouth, where they thrive and reproduce in the intestinal tract, interfering with
    food digestion and nutrient absorption, and causing blood loss and dehydration. The coccidia lay eggs called oocysts in the intestinal tract, and when the chicken poops, it sends those oocysts with the poop. The chickens that eat around that oocyst-contaminated poop are likely to ingest these oocysts through the mouth, where the eggs will be carried down into the intestinal tract, where they will hatch. Coccidiosis spreads very quickly, and very easily, and in a matter of days, an entire flock can get infected. It can be fatal if not treated.

    Symptoms of Coccidiosis

    Symptoms of Coccidiosis can vary. For a mild case, the symptoms are weight loss, diarrhea, and pigmentation loss. For a more severe case, the symptoms would be weight loss, bloody diarrhea, pigmentation loss, and it may look drowsy. An infected bird may also stand, away from the rest of the flock, with it's feathers fluffed up, with bloody diarrhea below it's butt.

    How To Treat Coccidiosis

    Treating Coccidiosis is an easy task. There are several natural ways to treat Coccidiosis, such as treating it with a milk flush. But the recommended way to treat the affected chick(en) is to use sulfa or amprolium drugs. You can also use Diatamaceous Earth in the food. I mix enough Diatamaceous Earth into the food to make it look somewhat white, and let the animal eat it at will.
    These drugs are administered through the infected chicken's drinking water. If you treat a laying hen using sulfa drugs, you must not eat the eggs for 14 days.

    How To Prevent Coccidiosis

    Preventing Coccidiosis is much easier than treating it. To prevent Coccidiosis, rotate the water and pen location regularly. This does help! Changing the topsoil in the pen yearly also helps by removing any buildup of oocysts. This works because, if you have two pens, while the flock is in one pen, the other one can be treated for Coccidiosis.

    Preventing Coccidiosis in chicks is even easier. Use medicated chick starter and clean the brooder regularly. This helps to prevent Coccidiosis from striking your chicks.


    Coccidiosis can be a very stressful experience for first time chicken owners, but it is something that puts your role as a chicken mom/dad to the test!

    Good article. The pictures of the pen #1 and pen #2 are not showing, but I get the picture of what you're supposed to do anyway. Read an article that said doseage for Corid 9.6% is supposed to be 9.5cc per gallon of water, how much is that in teaspoons or tablespoons?
