I've recently noticed a few bloody looking stools from my chickens. I'm not positive which one it is coming from. They all seem to be eating, drinking, and acting fine. We've only had our chickens since mid April when we got them as chicks. So this is all new to me. I've read a few things on here that it could be what's coccidiosis. But I'm not sure how to properly diagnose that and if I'm just over reacting. Help would be greatly appreciated.
