Last night I handled my 2 week old chicks fine, with no problems. I just got them 2 days ago and have given them a heat lamp, water, and medicated chick starter. However, this morning I went out to the brooder and there was bloody poop. I saw one chick poop blood, but this chick didn't seem particularly sick and looked healthy. All of them seem healthy, bright eyes, running away from me as per normal, however there was more than a few bloody feces in the pine shavings. What's happening? Just in case they have Cocci, I got my parents to run into town today and grab either Corid or SulMent, however the chicks don't seem sick and I don't want to unneccesariy treat them. The guy I bought them from said he's given them their vitamins and shots? What does that mean? He knows they are on medicated feed too.
