I have two 3 month old Khaki Campbell females. They will only bathe if I go and clean the pool out. I give them separate drinking water (have chickens too) and clean that everyday. But the muck up their pool very quickly with mud in the bottom and feathers floating (molting). But financially I can't clean out their pool everyday, that is a lot of water. So it has become a real battle to keep them out of my son's pool, which I keep a lot cleaner. Anyone else have picky ducks that will only bathe in clean water?
