Should I screw the stuff into the corner posts? Can I use my electric staple gun with long, heavy duty staples to pin it down all the way across the top and bottom? Possibly even the intermittent supports? Also, if were are doing the totally enclosed box thing for the run, which attaches to the front of the coop, and a hardware cloth apron is buried all the way around the coop and run, would you still bury an apron across the front of the coop? It will already be inside the perimeter of hardware cloth, so might we be able to cut that expense? And when we bury the hardware cloth apron, is 2" of soil on top sufficient?
