The last two nights in a row, we've found a single hen (two total) decapitated, laying in the middle of our coop. There is no sign of predator entry that we can tell. Is there any chance the roster is doing this? We have a 12x12 coop and only about 16 birds, one rooster. We live in Colorado, if that matters, and we're finding the heads in the coop, so whatever it is isn't even taking the heads. Any ideas or insight would be helpful! Thanks!
