I just happened to walk thru my kitchen and look out the window to see all my chickens flying, and thought a dog was chasing. As I got to the door, a bundle of feathers went flying past; as it turned out it was one of my chickens with a hawk, smaller than the chicken, wrapped around it. I scared off the hawk, and the hen was unharmed, though a little traumatized. I've kept them in the run since, hoping the hawk will forget about them. They are used to free ranging and unhappy with the confinement. I know the price of free ranging is predator risk; any suggestions on how to discourage the hawks?
