Yesterday morning I went out to check on my five hens and there were only three. I let them free range, on about an acre of oak trees and never had a problem. Only two piles of feathers were left, no blood or any trace. Could a hawk take two birds? We do have hawks around sometimes but they've never bothered the girls. It was about 10am, and they were only alone for about 30 minutes...I'm so sad. Just wondering what it could have been and how I can prevent it from happening again.
