I just put my 10 wk old girls in the coop. They had been in the house. Yesterday was their first day outside. This morning I found blood on the pine shavings in the coop. After watching, I see the chick poop and there's blood. I am hesitant to say that it is Cocci because they were kept inside with probiotics as well as electrolytes. They are still on chick starter feed as well. The chick is still eating, drinking, and behaving normally. Could it still be cocci?
