I found a ton of fencing at Lowes, but want to do this right the first time. They don't have true hardware cloth (near me, anyway) in anything more than 2' x 5' lengths. I know I need a smaller mesh for possible raccoons, but do I need it way below ground? I found a small 1/2" 19G mesh, but it's not galvanized which means it'll rust underground, correct? Can I bury 1' galvanized and then just use the 1/2" to overlap the bottom 18" or so? I'm doing a big run (10x10 planned now, another 10x12 extension next spring) so $$ is of course a factor, but I'd rather just do it once. Here are the two I was looking at: The 1/2 inch: http://www.lowes.com/lowes/lkn?action=productDetail&productId=92202-000080032-HF30100219&bc=c and the galvanized chicken wire: http://www.lowes.com/lowes/lkn?action=productDetail&productId=92679-000080032-PN20250120&bc=c My yard (and the coop) is adjacent to 300 acres of park and bird sanctuary. I've never seen a raccoon but I'm sure they must be there. We have tons of wild turkeys, and I've heard that there are coyotes around although I've never seen them. Am I better off just doing the whole thing in hardware cloth? Can I get away with doing the roof in something less expensive?
