I've had chickens for a year and a half with no problems, until today! My buff orp. rooster Twinkie, was really making a lot of unusual noise this morning. I went out to see what the problem was and saw nothing. About 15 minutes later Twinkie was still going at it. I went out again and a hawk came down right into their run then flew up and landed on the roof of the coop! I yelled at him but he didn't seem to care about me at all. I stayed out there a while, I thought he was gone but then he came back right in front of me. Twinkie did his job and got all the girls inside. The hawk was about half the size of Twinkie and didn't seem to want to challenge him and left. My chickens have a run but also have access to a field with an electric fence. Both the run and field are filled with apple trees, I was so surprised to see the hawk come in under the canopy of apple trees. I put all the chickens inside for a couple of hours before letting them out again. I haven't seen any more sign of the hawk and I've been watching all day. My mother gave me a shiny red and silver ribbon to tie on the run fence, it's what she and my father use in their vineyard to keep birds away. I don't know what other people do but I can't keep my chickens inside. It was too hot today for one thing but they also just don't like it. Good luck, I hope your hawk doesn't come back. Jen
