I built a 8x8 coop and wanted to know every ones opinions on what they used inside the coop on the plywood and 2x4's. I am trying to decide which will last longest. I know on Decks you have to restain every few years, but the stain goes deeper into the wood than paint that can get chipped off by the birds. I want to be able to hose it out a few times a year or as needed. Should I stain it or paint it.
