A predator got into our coop last night and killed the entire flock. It looks like it opened the door somehow and fit out by barreling through the chicken wire. 4 chickens were missing and 10 were dead in the coop. Any thoughts on a predator that would kill everything but not eat? We are in southern AZ and have coyotes (taken a chicken before), bobcats, and mountain lions. There was a small tuft if beige fur stuck on the wire. Your thoughts are appreciated!
