We forgot to close up the birds last night and ended up losing two of them. We think it was a hawk or owl. We found one of the leghorns in the neighbors yard with the head and organs missing. The other was one of the Reds. She was still alive, but had a bad gash in her side that was not fixable. We decided to put her down. I guess I'm a little amazed that this is the first predation we have suffered out here. Hopefully it will keep us more vigilant in the future. :(
