I am so sad. We keep our 4 hens in a chicken tractor but let them out into the pasture for a few hours when we get home from work so they can run around and take dirt baths. We've been doing this for a year now without any problems but some ravens killed my beautiful Spotted Sussex tonight. We thought a hawk had tried to get Babette my favorelle earlier in the week after we found her in shock with a lot of tail feathers missing. There was no blood on her and she didn't appear hurt just really upset so we put her in a pen by herself because the other hens started to harass her as she is still a little shook up. We haven't seen any hawks in the area so we let them out but my husband interrupted some ravens that had killed her, pulled all of her neck feathers off and started to feed. I immediately put the others back in their pen. I knew ravens liked to picked on small song birds but had no idea that they would attack my chickens, So now I'm afraid to let the hens out anymore. We found a dead chicken several houses down our road that had been killed the same way a month ago but we didn't know who she belonged to or what had killed her. Maybe we can use netting or wire to construct an outdoor run so they can still get some run around space?
