I always have coyotes stalking my chicken coop. I now have a guard donkey. You want to talk about a vicious killing, you should see what a donkey can do to a coyote or any stray dog that enters the property. He keeps all types of canines off the property. Although, we did have a coyote come into our backyard in the middle of the day! Yes, right near the childrens' swingset. My alert wife ran out the door with the shotgun in her hand. I was in the garage, and heard 3 shots ring out. The shots were so fast, I thought my wife had an automatic shotgun. I never heard a pump action fire so quickly. The children were inside, but her maternal instincts didn't lilke the fact a coyote was in the yard in the middle of the day. Of course, the Donkey was in the pasture, and the coyote was smart enough not to go in there! Anyway, after seeing that the coyote could stalk children, or so I think, I now see them as a serious threat, especially, if I see them during daylight.
