How do I keep Predators from digging underneath our chicken run

Did you use hardware cloth on that whole thing even on top

We buried interlocking concrete bricks under the perimeter of their setup. These bricks go down about 6 in. We’ve seen evidence of digging attempts, but nothing has dug down further than the bricks so far.

yes pull over the top and attached at the base on each side

I do a similar apron around my pens as @Molpet has done. The exception is I buried the HC with about 6" soil, then layed down 2" of concrete on top of the soil. Nothing has even tried to dig under my pens.
