I've lived on a farm all of my life and have never seen a coyote kill a calf and was wondering if it does actually happen. I've heard neighbors claim that coyotes have killed their calves, but I'd say what really happened was they don't check them very often and had one die naturally and coyotes did what was natural for a scavenger and ate it. I've heard of them killing sheep and that seems like it could easily happen, but a cow just isn't going to let a coyote near its calf.
