My chicks have blood spots in their stool but the stool is not watery in fact it seems to be too well formed and hard. (more like very tiny people poo than bird poo) The blooded stool is not constant, the birds are showing now other signs of illness. They are chirping happily, eating, drinking and playing. The local feed store is out of cocci meds and my wife called the other feed store where we got the chicks and they said they don't carry meds or medicated feed. Does this sound like cocci to you and should I medicate? Does tractor supply carry the meds and what should I get?
