I was on vacation and my daughter was taking care of the chickens. They free range and have so for 3 months now. She came home from work and found 1 in the run. The darn chicken was in the run w/o any netting on top of it, by herself. My brother in law came over to help her (she was so upset) and they put up netting over the whole thing. Sat a ladder in the center to help hold it up w/o sagging. She left to get more feed the following day, came home and the hawk was sitting on one of the stakes that hold up the wire. She started banging on stuff and nothing made that hawk fly away. She said it felt like forever but was probably about 30 secs before it left. It flew down and slammed against the netting and killed another chicken. She left them in the coop for a day and today when I got home left them out. Went outside and 1 was crying like crazy. I took off running and the hawk flew away. Thank God they were under the pine tree. After this long story, what can I do? We are redoing their run tomorrow and making sure the top is made form wire or something strong. Its like it taunts them. Do scarecrows work? How bout bb guns? I feel terrible leaving them in the coop all day. If I do put up wire on the top of the run how do you keep the hawks from sitting on it and taunting them more?
