Well as I have said I don't know what got my hen. I think that the fact that the head was severed and left laying next to the body would mean something to the right person. I looked at the neck and, as I said previously, it was cut nice and clean. I don't know if that would just be a coincidence or if there is an animal that would do that. What ever it was it ate only the meat of the back of the bird it did not disturb the internals, and there was only enough feathers removed to get to the part that was eaten. I know that nothing is 100 percent but I have hunted racoons and opossums as a kid and they normally don't come out until an hour or so after sunset, and since my hens are always on the roost just before dark, and this particular hen, being the oldest of the group, usually beat all the others to bed. She would be on the roost an hour before dark every night. So I know she was killed during the day. I examined the head and there were no marks on it. It just looked like someone laid her on a chopping block and chopped off her head. She was old and slow so I think a cat or something could have done it, we do have feral cats that show up every so often, but I don't know if a house cat would go after a chicken. We have a cat and my neighbors have four and they run around all over the place and have never even looked at a chicken so I don't know what to think. For now I am keeping the chickens in their coop. It is large and well ventilated with good light so they can just stay in there until I figure this out.
