Sad Tuesday for me. So I went to put the chickens to bed (close pop door, close up run--they free range over that backyard during the day). I open the coop to put their waterer in, and one of my barred rocks, Ruby, is lying upside down, headless. Whatever it was tore it right off. Didn't appear to eat anything and there were two eggs in the nesting box. What kills chickens without eating them? The other three were roosting and fine. All's well this morning. I've had them for three years and this is the first one I've lost to a predator. I've seen hawks, an opossum and recently a raccoon, so maybe it was the raccoon, but I would think they'd eat her. Help!
