I'm so glad Snowball is ok. She is so cute! I've had my chickens free-ranging for the last year and never saw a hawk. Then last month I had several attacks. I was also working on the computer when I heard lots of screeching. When I got out there a hawk had one of the RI Reds cornered. She was so brave. She was standing as straight up as she could and just yelling at the hawk. The hawk was swaying back and forth low on the ground. That sucker didn't fly away until I was a few feet away even though I was yelling at it the whole way out there. Then I had a little Ameraucana get grabbed but she got away only with a bunch of feathers yanked. I covered the entire run with green plastic garden fence from Home Depot. It was expensive but so worth the peace of mind. The other thing I did was to put up a 12' high colorful windmill and a hot air balloon garden ornament that spins like crazy. I also put scare crows on the fence posts where the hawk had sat one day and I put a human size scarecrow hanging in a tree so it sways around a little. I'm not sure if it's luck or if these things are working but I haven't seen a hawk since. The girls also are so much more aware of other birds now and they run for cover a lot more.
