Hi, new poster here. (I've been reading for months, getting lots of info and answers. I guess that makes me a Lurker?) This morning I found one of my Wellsummer hens dead in the run. (Half covered with netting, half not). It was obviously chased, I found a trail starting with a clump of tail feathers and ending with a headless, tailless body. I found the head by the coop door. Not eaten, mind you, just killed. I have 6-ft high chain link around the area with no obvious entry holes. Had previously been a dog run and the previous owners had it fortified pretty well. I know there are hawks and possums around, and probably raccoons though I've never seen one. What kills a bird and rips its head and tail off and leaves the body? Any ideas?
