I came home from work tonight to find all of my chickens cowering in the coop. They did the alert clucking when I walked up to the coop. I talked to them and they settled down. I knew something was wrong. I did I walk to the pasture, and only about 50 feet from the coop was feathers everywhere. A trail of them led to my americauna hen.I also noticed a tail feather from one of my roosters. It seems he tried to help his girl. I got the dead hen out so they did not have to look at her any longer. I looked over the flock to notice one of my buff orpingtons hiding on the roost. Her back was picked and cut up. I treated her with some blue-kote and talked to her. She sang quietly to me...she is so sweet! My question is what does one do to protect a free range flock from a hawk?? I have always said quality of life over quantity is more important. They love being out, but I sure don't want this happening again!! Hawks are the only predators that I have have had a problem with. I lock them up tight at dusk. Any suggestions??
