The guys are right when they said to get a good trapper on your place to get your coyote problem down to an acceptible level. Once he gets the problem under control then an ongoing program of predetor control work should be enforced. Nobody is ever going to kill all the coyotes out of any given area. Not all the coyotes on your land are killing stock. What your after is controlling the population and taking out the problem animals. Once you reduce your coyote population down a bit I think you'll see a definite decrease in your stock predation.
