Hello, I am currently working on converting an old horse stall into a chicken coop and was looking for advice on how to best make this predator proof. We do have foxes and raccoon around (We even found a chewed up deer femur in the stall!) The plan is to lay a plywood sub-floor on top of the landscape timbers that would stretch from wall to wall and prevent digging from below. Should we also lay some larger gravel? I cannot figure out how to block access from the gap between the stone wall and the supporting roof timbers. I am thinking around erecting a plywood wall that attaches to to sub-floor and the side supports to close the gap. This wall would run up to the rafters. What is the best method for securing hardware cloth around the rafters? Will i have to be making lots of cuts or is there a better technique? Any advice would be great! I prefer to not lose the chickens to predators!
