I have had this huge hawk in my yard almost everyday for the last two weeks, and I'm sure he is after my chickens. I have 2 silkie's (one is a rooster) and 2 barred rock hens. My husband hung cd's all around the trees and & i'm wondering if there is anything else I can do that would help. A few days ago he was in a low branch eating a bird & staring at me through my kitchen window...almost like he was warning me- very creepy. I was thinking about getting one of those fake owls? I have been keeping my chickens cooped up in their run because i'm afraid, but I feel so bad for them. How long should I keep them locked up?
