I’m trying to decide what kind of plywood I should use for my coop my plan is to use 2x3 framing lumber for the run and frame of the coop but I’m not sure if I should use OSB plywood because it’s cheaper but then I would have to put siding on and seal it or if I should use just normal sheathing plywood also what thickness should the plywood be? (price is a main factor in this)
