Hello, I am about to begin construction on a new coop. I have noticed the Knotty Barnside paneling being used in many applications. My question is does this paneling require something such as an OSB to be applied before the paneling? It seems as if the backside of the Knotty Barn siding is a bit fiberous and was wondering if this could harm my hens if not covered. If this in fact is an issue I thought about just using the OSB on the inside as walls. Any thoughts would be greatly appreciated. Thanks!
