Hello BYC'ers. We are currently building a barn style coop (11'x11') pictured below: My question is twofold. First: for the run (which will be 200 sq ft, 7' TALL sloping to 6') do we need hardware cloth on the top of the run? We are planning on putting up chicken wire for the sides with hardware cloth in front and buried 2' into the ground, the coop itself is on a concrete pad, so we're not worried about digging there. Just wondering if the hardware cloth on top is necessary. My second question is: My DH bought exterior OSB (??) (I'm positive it's not plywood) and I have read mixed reviews on it. It's too late to take it back, so I was wondering what's the best way to treat it and keep it lasting as long as we can? Is coating it in several thin layers of latex paint okay? I read on here to pay particular attention to cut joints and edges - so if we were to do that, would it be okay? Is there something we can do to "seal" it before painting it to make it more moisture resistant? Thank you SO much everyone for your help!!
