A neighbor has been keeping chickens in a home made coop that sits right on the ground with no base. The chickens have been in there for about two months. They poop there, sleep there, and eat in there. He throws the food right on the same ground they poop on and they eat off of it. He is going to butcher his chickens and wants to give me one to eat. I'm wondering how safe that would be considering how they've been raised. Is there anything to worry about?
