So I had 24 chickens the free range and have a coop they go into at night. One night 3 never showed up and I thought they might the next day but they never did. Now this morning I went out to let them out and I have a lot mossing. There is a hole on the side of the coop that looks like something dug. There are no bodies or blood but a ton of feathers both in the coop and out. What kind of predator is this?
