This is the second morning in a row I wake up to find an eaten Silkie carcus in my coop. Something is waiting for the automatic coop door to open at sunrise and going for the girls. The head and breast meat was gone on the first one. The second one was picked clean internally, all the breast and abdomen gone. I’m going to set up a trail cam and deactivate the automatic door, it’s solar powered. I’ve had chickens 5 years now and never had anything like this happen. What predator could be doing this?
