Hi, I am researching to build my coop now. I want to do it right from the beginning, particularly when it comes to predators. We have lots of foxes and raccoons and they are big time diggers! Can anyone please recommend what materials they use to construct both the coop and the run to protect against predators, inlcuding hawks (we have lots of those too!) What materials are you using to for the coop, for latches, for fencing? I know nothing is 100% proof, but i want to do my best! Thanks!
