Coyotes can and do chew on newborn calves in my part of the world (Colorado). My cowboy friend has a few every year that are missing tails, ears, etc. when they are newborn out in the field and the coyotes attack them before they can get up and nurse. He has 150 cows out on winter range (and manages another 350); there's not any good way to protect them.
