I have seen one coop https://www.backyardchickens.com/web/viewblog.php?id=7019 that had galvanized roofing on the bottom and barried into the ground. Is this ideal? It seem that it would be easier to put in the ground and if something did try to dig they could not grip it and pull it like if it was wire. What do you think & what are you using? We are subject to foxes, coyatoes, dogs and maybe even a cat. These are the list of animals I have seen through my house windows there maybe more.
