I have had hawk attacks, but this looks different. The body is found in a different place from the head, one time intestines were with the head, body 20 feet away. Sometimes the flesh is striped from the neck with the head still on, the body is never eaten, sometimes a big hole in the breast. Is that characteristic of any certain animal? Sorry so graphic, but I'm trying to figure out how to make my pen safer. I put them in their house at night.
