I just chased a hawk off the carcass of one of my ducks, but she was already dead by the time I got outside. I've now lost three chickens and one duck since Sept. to a hawk. All my birds are free range, we don't have a pen for them that we can cover, they go in a coop at night. Any ideas what I can do to keep the hawks away? Will a dog keep a hawk away, or just larger prey? I dont have a dog, but want to get one, as we do have coyotes, foxes and skunks.
