I feel guilty and sad. For a few days I have kept my flock cooped after noticing several migrant hawks in our area. Today being a holiday with the whole family home, we went ahead and let the flock out. We were active outside and things were OK until we went in for a few minutes about 3:30. It wasn't 5 minutes, just time enough to spread cheese on a bagel! I heard a ruckus outside and stepped out, not surprised to see our meat/feather roosters squabbling in their pen. DH and son came out and went for a walk. I noticed someone missing, our 10 wk old mutt roo Tigger. All the birds were clustering near me, eyes skyward and growling. Finally I found Tigger's remains 50 feet from the coop under a cedar tree. There was a Cooper's hawk in a nearby treetop that flew a short distance away when I approached. The hawk had eaten the crop and neck meat, leaving the head on the spine. The body was otherwise intact. The hawk hung around until I boxed the remains for a funeral. Thus far I have lost two young birds to raptors. None to the various toothy predators I know are thick in our woods. Question for others - are flock guardian dogs less able to protect against raptors? I think my dog is as frustrated as I am. I guess everyone is going to stay cooped for a longer while now.
