I'm getting ready to build my run, it will be 8ft x 20ft. The boarder on the bottom will be 2x8x10 and I plan on going down 1ft with 1/4 in galvanized wire mesh and burying it and hopefully nothing will try and dig down a foot to get in. I'm then going up 1ft with the same mesh from the 2x8x10. Now I'm not sure if I should use chicken wire or something a little stronger up the sides to the roof this will go all the way around the run. I plan on covering the roof at a slant and using some king of durable roofing material. The predators I'm looking at are hawks, opossum, fox and raccoons. I think this should hold up, the only thing I'm worried about would be the chicken wire. Any comments would be greatly appreciated.
