My predators are usually hawks, but I had a chicken killed today and cannot figure out what did it. There was no blood at all or any wounds that I could find. She had two bald-ish patches on her back (which she was lying on) and seemed to have been dragged up to a small hole in the wall of the barn (not the coop, just a place my hens hang out). I think I saw some paw prints, but they were very faint and hard to make out. Does anyone have any idea what my predator might be? I'm trying to figure out how I might prevent any further casualties!
