I'm building a new coop to house ducks, geese and chickens. I just got a kind of crazy idea... I have this old bathtub laying in my back yard from a bathroom remodel. I was thinking that maybe I could put it in my coop for the ducks at night. The coop is elevated off the ground so the tub could be recessed and level with the floor and it would be really easy to clean out... just pull the plug!!! Would a tub of water be problematic for the chickens? Would they run the risk of drowning in it? I could separate the coop into two parts if that would be better... So what are your thought on the bathtub? What is your experience having ducks and chickens together? Any special housing accommodations?
