Firstly - I free range my hens. I know predators are part and parcel of that choice. That being said, I've got a couple of large hawks hanging around, maybe a breeding pair, beautiful birds. Except when they take out one of my girls. They love to sit on a utility pole in the pasture and monitor the run, waiting for me to turn out. The run door doesn't open if I'm able to see a hawk. When I see them, I go out and chase them off - usually they don't go out of sight. I really don't want to kill them, just get them to relocate. Two states over would be dandy. A game warden told me he knows of some local chicken farmers having good results with laser pointers. I might could use it from the back door and not have to go out to the pasture several times a day.
