Run and coop have been done for a while, but just went thru the effort to bury 18 inches of 1x2 welded wire fence around the run. Wow...lots of shoveling clay. Maybe the clay ground would have been enough. I did not want to chance it. SO Attached wire with wood screws and big washers all along run, dug up ground, (clay), then layed wire and recoverd. Should keep the coyotes, coons and neighbors dogs out!
