I'm working on my design for my first coop and run and I'd really like to bury wire cloth under the run to prevent foxes from get in from below. I had buried fencing into a trench around the perimeter when I laid out my vegetable garden and it was truly agony. CT soil is glacial and very rocky. What I envision is to dig up a layer of topsoil, much like cutting sod, putting down a layer of wire cloth and then putting the sod layer back over it. I'd turn up the four sides of the wire and sandwich it between the base board and my run framing wall. Although I realize the grass would be gone fast, it'd be nice to start them out with a 'lawn.' Or combine the grass with a sand filled area. Has anyone done this? What material would serve this purpose best. I would not want to go through that if the wire would corrode and disintegrate underground. I'd appreciate any insights or knowledge. Thanks!
