We recently purchased a coop for our chickens. The fence is nearly done and the girls are more than ready to go outside! I don't want to ruin the wood, as we want to have this coop last years and years! The inside is unfinished wood, I was thinking if painting it so I can scrub is down/protect the wood. Any suggestions on what paint to use? I'd hate to paint and then find out "Oh, that isn't safe for chickens."
