I was wondering what animal that might be because my neighbor call me and said he found one of my chickens in his yard with the head bit off and all its insides eaten. I have chicken wire buried as a fence with 2 strands of electric around it. Also there is netting over top.I have them locked into a coop that i built. I have wire all around the coop with a regular door with a lock on it. The door hasn't been closing the whole way, its been open about 2 inches toward the top.
