My hawk problems are pretty minimal but I agree with Dave about teaching your birds to be hawk aware. The more they encounter a hawk the better they get at evading it. This doesn't at all mean that the hawk will never snag one of my birds. It just seems like common sense IMO. Why do we trap train our birds? Because they're smart enough to learn how to enter the loft to eat and rest. If they're smart enough to learn how to trap I think they are smart enough learn how to evade hawks. There's just more of a risk with training them to evade hawks, Lol.....
