A couple of weeks ago we found at Home Depot 7/16" OSB with Camo vinyl on one side. It worked perfect for a winter roof on our coop. The girls seem to really like the extra protection. Tonight we built two wooden frames with plastic attached and screwed them under the hen house on two side. Leaving the side next to the building open. Trying to give them some protection from the wind and rain we get here on the Oregon coast in the winter. They were very curious as to what we were doing. We'll see how it works tomorrow.
