My children have always been told the same thing - if you wont drink from it, neither should they. For the ones on the ground, the feed store hangs wood suspended above the waterer....since it dangles it wil swing if they try to getup there and they don't like that. For anything the ducks get into, I don't worry about since I have a lot and a bath tub that they wont use for some reason, and the chickens and sheep will drink from that. Otherwise the waterers are all scrubbed every Saturday and Wednesday, bleached and Vinegared.
