I just went out to let my chickens out of the run to free range until bedtime only to discover all my chickens pecking at something. That something was one of my Polish hens. It's head was completely ripped off and it was also completely gutted. There were feathers all over the place. We've lost some to Cooper's Hawks and so has our neighbor (we actually saw the hawk kill them). Can the hawks actually rip the head completely off? I can't find the head anywhere. I've looked in the coop, all over in the run and all throughout the backyard. There is no way it was a dog or anything like that because the run is secure except for the top.
