How to diagnose coccidiosis in chickens

  1. DuckRunner
    What is coccidiosis?
    Coccidiosis is an internal parasite, which rapidly multiplies and then damages the lining of the chicken’s intestine. The parasite bloats the intestines and can even take no symptoms before the shock of it’s death comes.
    How do I prevent it?
    What are the symptoms?

    droopiness and listlessness,

    loss of appetite,

    loss of yellow color in shanks,

    pale combs and wattles,

    ruffled, unthrifty feathers,

    huddling or acting chilled,

    blood or mucus in the feces,



    and even death. Other signs include poor feed digestion, poor weight gain, and poor feed efficiency. Some symptoms can be confused with other diseases. For example, necrotic enteritis is a gut disease that also causes bloody diarrhea.


    How do I treat it?

    First method is Corid, the most popular and useful method I have used.
    You can get some from this link:

    How to use it is in the writing below


    How do I prevent it?

    • Medicated starter feed OR vaccinations. DO NOT use both since they render each other ineffective. Use one or the other.
    • Apple cider vinegar in water. This extra acidity will help keep the cocci cysts from forming in the gut. Also, some sources say garlic works as well. Some farmers prefer these more natural methods of prevention.
    • Above all, good management! Don’t be a lazy chicken farmer (is there such a thing?) Cocci is passed by infected chickens in their poop. As the other chickens peck around the barnyard, they can ingest infected feces. With this in mind:
      • Clean waterers and feeders every time you refill them
      • keep bedding clean and dry
      • control rodents since Cocci can be transferred by rodents (although it doesn’t infect them)
        • when handling infected chickens, clean clothing and footwear since Cocci can be transported on them,

    Seminolewind’s add:
    If a chick looks sick, and we know what sick looks like, there's a 99% chance it's coccidiosis with or without dehydration and starvation. If you medicate, make sure they get it!

    Only one of 6 types of coccidiosis cause bloody stools. You can't say if there's no blood it's not cocci. Same goes for medicated feed or cocci vaccine. These do not guarantee that your chick is not sick with cocci. They are only preventative. There's no realistic way of removing cocci from a chick's environment.

    If your chicks look sick, make sure they arehydrated, have calories, and possibly treat forcocci. They go downhill fast.

    I've had good luck with tube feeding and/or using a 1 ml. Syringe and inserting it to the back of their throat. This way you have gonepast their trachea.
