Nope. start hunting them, or atleast shooting at them. They are smart and will learn. However, you need to kill one. In my experience, once they start losing pack members, they start learning that you are a predator and will not want to be around you.
ALso, don't assume that just because you move to another part of your property, that its "away from where they live" or that coyotes across the road are another pack. These things travel all over the place. a road isn't going to keep them in a certain area...
