how to stop digging predators?

I believe members of the guinea fowl forum have had good luck with hot wire for bears, Not around the run, the hot wire is used to "fence" in their yards, originally "baited" using bacon so they touch it with their most vulnerable parts. You will have to fix it a couple of times, but it works.
