I didn't! Apparently, there is EXTERIOR and INTERIOR plywood - I had to do the supply run for the coop - so I just asked for plywood (though I am 99% sure I told them what I was building). Point being - we must have ended up with the interior stuff, because it has started raining, construction is still underway and it is not painted yet, and now there is a warped spot in one of the walls with about a half inch gap between it and the stud - right on the corner! Does anyone know if it will dry out and shrink back up to normal? Or should I just start planning on being able to fill that gap so I don't end up with a random draft in my coop?
