I still think a Great Pyrnees is a better fit. They can keep predators away without much guidance. From what I've seen, they kind of lay about, then perk up and off they go. Minutes later they come back. It's obvious they've run.
My brother in law used to manage a chicken and turkey farm. The owner had dropped off a couple of Pyrnees. The BIL says he saw the Prynees chasing coyotes away from the barns.
