We have a whole lot of red tails and a few bald headed eagles and owls too I'm sure. All my runs are covered except for the Welsummer's run. The chicks were in a little section of chicken wire that was seperate from the others but it was covered. The outside of that little section was made out fence that has 2x4 inch holes and whatever it was pulled the cockrel through 1 of the holes. The poor little pullet was terrified, when I went out there she clung to me and kept hiding between my feet. And that's strange for her, she's doesn't like people anywhere near her and certainly doesn't liked being touched but she snuggled against my leg and actually wanted me to pet her. The poor little thing is all alone now. I locked her in the coop for the night so nothing can get her.
