But a pack of them can scare the heck out of predators. It's not just one dog; I have 28. I've had no issues with coons, opossums, or the like. Even a fox came around but left in a hurry.But I agree about coyotes. About all you can do with that is a camera and lay in wait with a rifle. I also use chain link fence instead of chicken wire around our lot. Inside the coop is 1/2" mesh wire for individual lots.. Fortunately, knock on wood, I've not had to deal with coyotes... yet. Hawks are more of an issue for me. I feed the crows, and they keep the hawks run off. It's nice to be able to use natural predators who are not a predator to the chickens. Love our crows!
