Not buried - it's built like a truck. Trying to walk on the boards only was unrealistic for a klutz like me, so I put plywood over that, in both the coop & run areas.Yes, it’s amazing that something as small as a weasel can kill a chicken! Weasels follow rodents through their burrows, so I would definitely be concerned about mole burrows near your coop. Do you have buried wire around you coop or an apron?
