Well, I just learned something new here. I had no idea a racoon would kill a chicken. Do opposums kill chickens? Or go after the eggs only? I've been trying to figure what crawled up a 6' chain link fence and killed one of our hens last Fall. I hadn't thought either would kill/gut a chicken and thought maybe a fox, but I don't think they can climb chain link. The entire area is covered with chicken wire as a 'roof', but there were a couple of gaps here and there. (closed up since) I've found black snakes in the coop (twice yuuk!) but they seemed interested in eggs only, so I guess they fall in the category of pest. So do opposums fall under category of predator or pest?
