My ducks and hens share the same large henhouse and eat out of a 3gal. metal gravity fed feeder and the same for the water, The ducks with running from feeder to waterer have made the floor of hardwood chips like thick mud (no doubt feed & water dropped there too). I plan to over winter 9 ducks and 15 hens in this lg. garden shed. Anyone have any ideas of how to keep the floor dry?
