I think anything around the bottom to prevent digging would be good. Cinder blocks, 1/2 inch hardware cloth, concrete. Concrete would be more permanent and a pain to break up if you ever decided to move your coop or expand it.I have a trail camera facing the front my chickens coops, but I have so many in different places the camera can’t catch them all. I think it’s going behind the chicken coops if it’s not going in front of the camera. I’m located in west Texas. I do also have hardware cloth around my coops. It’s all on the roof and upper part of the walls mostly for shade when it gets extremely hot. I’m putting another layer of wire over the one I already have too, so the gaps will be a lot smaller but also harder to pull off if it’s trying to get in that way. I’m also trying to dig a trench and pouring concrete around the bottom so it can’t dig underneath like it’s been doing. Do you think that would work?
