I had a rather large rooster killed two days ago and then my duck killed yesterday. I always put them up at night but this was in the middle of the day when I had let them out. Yesterday, I saw a bird on top of my duck and when I ran out to it it took off and appeared dark grey to me, however 30 minutes after that I saw a red tail hawk circling. I saw the bird fly away from about 120 yards (the one that killed the duck) so it was hard to get a good look. Could this have been an owl in the middle of the day? Or does this look more like a hawk attack? I'm assuming the same bird killed the rooster the day before, its head was almost completely separated and body which was laying right at the open door to the coop. I am really heartbroken about my duck as she was so nice and loving toward us. I am located near Charlotte NC and any insight would be appreciated. I may have to get a guard dog as I hate to keep the chickens pinned up continually.
