I would love to hear your thoughts on the wire. I am running the whole run walls in aviary wire with the lower 24" in hardware cloth as well. The chickens would almost never be kept with the doors to their secure coop left open to this run. But we do have regular visitors of raccoon and opossums. I have started by putting the wire on the outside of the run but it looks kind of tacky and is a pain to stretch smooth. Would putting it on the inside of the 2x4 over built structure with screws through bottle caps as fasteners be strong enough? I plan on having a walk right next to it so the scratches off the wire might be an issue too.
