We've just about completed our coop and run, but we're still working out the best ways to predator proof. The run is 12' x 12' made of chain link kennel panels. We want to put a roof on it and are considering hardware cloth. We're wondering what other people have done. Do you think we need to build a wooden frame to go over the run? Will we need to support hardware cloth across 12 feet? What's the best/easiest/strongest way to attach the cover to the chain link? Thanks for any and all advice!
