Actually, weasels will gut the bird and leave the meat...looks like what you'd see in a grocery story meat case. Minks will do this, too. Both hunt during the day. Hawks will often tear off the head and eat that, though. Last year on Thanksgiving day we lost a hen to a falcon. It was the first and only time I ever saw a falcon up close. Despite the fact that we were sorry to lose our hen, it was still exciting to see the falcon, as I had never seen one except in pictures. And it must've really been hungry to take on a standard size hen. The red tails here don't seem to be very interested in our chickens for some reason...mostly Cooper's hawks and Sharp Shinned hawks.
