This is my second post to this site and really appreciate any and all advice given. We're building a small barn/coop in preparation for chickens in the spring and are looking for suggestions for flooring. I've heard that chicken manure will rot a floor, so should we put a subfloor on top of our 3/4" OSB? If so, what would be best? Also, should we paint the floor for easier cleaning or would a water-based deck paint be toxic to chickens? Thank you in advance.
