No, Coccidiosis is a parasitic infection of the intestinal tract(thrives in damp/warm conditions,that is why chicks in brooders are susceptible to it). Almost all chickens have some cocci in their intestines,sometimes they have an overload and need medication. Coccidiosis is spread through droppings which get into feed/water via droppings. If they have cocci,apple cider vinegar will not help. Coccidiosis kills very fast,the only thing that will help is Corid(amprolium).I spoke to a local organic chicken farmer today about my chicken problems, possible cocci, and she said that cocci is spread thru the water. She said to change the water a few times a day to make sure it's clean and put a little bit of raw apple cider vinegar in the water. That is it to treat the cocci. She also talked with me about protein and how my rooster is so pale. She said that it usually a sign of protein deficiency and to give them eggs. I told her I gave 6 eggs to my six chickens and she said that was too much protein. Too much protein can cause the same symptoms as a protein deficiency and too much protein can kill them. You might want reduce the amount of protein. I'm going to pay close attention to the protein consumption now.
