I've heard, Rooapalooza, that if you do that and put some heavy material, such as rock or even dirt, on it, it's a good deterrent. My coop is closed in, but I worry about something digging into the run, when I'm gone. So I'm gonna screw some 1" chicken wire to the bottom of it, let extend out about 1'-1 1/2' and pile some small rock on top of it. I buy this 3/4" rock down the road for about $15.00 a yard. It looks nice too. If any thing, its gonna hurt what evers paws is trying to dig thru that wire, thus a deterrent.
