I'm building a little shed for my ducks to live in, roughly 8x8. The floor will be wood framed and raised up off the ground a little bit. I'm not sure what to use for the floor. I want something I can easily hose out, it needs to be water proof. I thought about ceramic tile but I think the grout lines would be hard to clean. Other ideas? Maybe just a piece of outdoor plywood with a heavy coat of floor paint?
