For me many predators. I have lost birds in the past to a bobcat (caught), fox (caught), coyote (shot with bird shot, ran off), hawks and owls. My coops and pens are now pretty predator proof. I haven't lost a bird to a predator in a long time. When I free range, I'm usually out working on the coops and fences. I have seen coons, eagles, possums and skunks but they haven't killed any of my birds. I do have several game cameras on my property and usually see a predator on at least one of the cameras most nights. Most of the predators here roam around at night, especially in the summer months because it's so hot here during the days.
