I found on of my japanese blacktail hens laying on the ground with her chest torn open and her head pulled off which i found about 25 ft away with a pile of feathers. My yard has a 6ft privacy fence around it with No holes on the bottom so nothing can walk crawl or dig in. So it had to be a cat or a hawk right? My first thought was hawk untill i found the head so far away. my experiance with hawks says they grab and go. but there is nowhere for a cat to ambush near where the attack took place. I cant figure out what it was. What do you folks think?
