If you have a neighbor who shoots at the coyotes that will definitely help encourage them to stay away. That and a good dog who is big enough and capable enough to take then down are the only things I have found that will keep them away. Otherwise, the presence of chickens will bring them and everything else out of the woodwork. I am lucky enough to have a neighbor who owns a big male Catahoula dog who will run down and kill coyotes any chance he gets. We went from having coyotes right in the yard in the middle of the day to no coyote problem at all since Tex came into maturity and started patroling lol!
