Coyotes are #1 most hated in my book. I've dealt with some big packs in the past that would take weaned goat kids right out of the pasture in the middle of day. Rip a pregnant ewe open just to get the unborn lambs and kill my beloved house raised goat at four years old. I hate 'em like nothing else. #2 Rats. Nasty vermin. The old place I lived at, they were there from before I lived there and they are just vile, destructive pests, leaving feces and disease behind.
