If the predators are under control and there is heavy cover you have nothing to worry about. Also, its always best to shoot most of the roosters out of your spots. One rooster will breed many many hens. But when the cold weather hits, the rooster will run the hen out of the heavy cover because the rooster is more dominant. You can guess what happens to the hen from then on. The only thing you can do to save those birds now is shoot every fox,coyote, and bobcat you see.
