Did anyone use Tyvek wrap under their siding? What is the consensus on type of siding used? Where is the cheapest place to find windows for my coop? I am wanting to put at least one on the west, east, and south side of my coop. Anything wrong with that? This is my first time ever building a shed or coop before. So far, I have the base of 2x6 connected to 4x4's that are cemented into the ground.
