I have a small backyard coop for a small, backyard flock. The flock has 2 bantams & the rest are standard size. The coop is 4x4 & the run is 4x11. Can I put a waterer in the coop? Should I put it in the run? What about the feeder? I'd like to avoid having mice/vermin with their fleas inside the coop. Suggestions? Are there specific feeders and waterers that are better than others? thanks!!!
