I know there are tons of threads about this, but I am in freak out mode and just thought this might be faster. I just went out to the coop and found on the droppings board one poo splatter that is straight blood. Just one. Don't see any in the run. But I am freaking out. Should I treat all 6 birds for cocci? I am being a nutso, I know. I am about to go back out and see if I can tell which one it was. They all are up walking around and crowded around me when I walked in. Just so scared! Do I need to change out litter and bleach coop or anything like that?
