There is no way that adolescent possum could have lifted the carcass without tripping the pan. I think a canine did it, because it cleared the 4' tall chicken wire fence, with the bird in its mouth. I did not find feathers. Anywhere. It took the carcass and fled. Did not touch the canned dog food that the possum took the next night. But the possum could have been what was eating the entrails out of the birds. I don't know, though.
