I see there are 2 basic ways to protect the run from digging predators.. bury hardware cloth a foot deep around the perimeter or use hardware cloth as a 2 foot apron around in on the ground... does one work better? just trying to figure out which way to go.. I'm thinking the apron would be easier to do but I wasn't sure if its as effective? Any thoughts.. the run is 11 x 8 feet.
