Hi there! We inherited a 20x30 dog kennel chicken run and I just put a new coop in it and now want to cover it but I want to have it be predator proof. My main concern is raccoons! I have some corrugated metal sheeting I want to put over the coop in the run to keep it out of the elements but I’m having trouble figuring out how to cover the entire run and have it be predator proof. I want to use some kind of hardware cloth (I added a 1/2 inch skirt to the bottom of the run) but the run is so wide it would sag. I’ve seen people use pvc to arch over the top but again it’s so wide this seems unlikely I can do this. Am I going to have to use wood and dig in support beams to really make a stable roof? Any help or ideas are appreciated! I added a couple pictures of the space.
