We had a pair of red tails take up watch in a dead tree overlooking our backyard and chicken coop/run area. Our hens would go out to free range a couple hours each afternoon til sundown. We never saw him swoop or attack, but as someone said, it was not if...but when it would happen. Knowing that shooting it to kill is illegal, we discussed how to frighten it away. Our oldest son came out of the house with a bottle rocket and roman candle left over from July 4. We watched as he walked toward the hawk's perch, getting within about 50 yards, he set off the roman candle, and with the first flash and boom, the hawk left and has not returned. Happenchance? Who knows? Anyway, we didn't kill him or intend to, but we intended to make him find other targets, and I think it worked. ~G Btw, we haven't let down our guard--we check the dead tree and nearby woods daily, wondering if he or a cousin will come back to haunt our hens.
