I came home tonight to find a rather large pile of feathers. Both of my bantam girls are missing. They always fly out of the chicken yard but stay right by the fence. I know we have both hawks and foxes around (we live in the woods). I think that it was a hawk. We had a near attack about a week ago while they were free ranging. I was able to scare it off & all the bantams were safe. Is there anything that I can do to protect the rest of them? I have read that fake owls work. Any suggestions?
