I had something get into my run a while ago. It got one bird and only ate the head and neck but left everything else. It scared the rest of the birds enough to have them fly out of the run because it is only partially covered. We locked the chickens in the coop( it was getting really cold anyway) for a couple weeks, left the dead chicken as bait and my boyfriend set up one of his small kill traps because he thought it was a weasel or mink but it hasn't come back at all! Does anyone know what it might have been?
