Ducks are waterfowl with strong motivation to bathe and swim, making water access a fundamental welfare requirement in duck farming systems.
Water access for ducks is not a luxury but a biological necessity. Ducks use water to clean their eyes and nostrils, to soften food for swallowing, and to maintain feather structure. Without adequate water access, ducks develop eye infections, nasal blockages, and matted plumage that impairs thermoregulation. Behavioral evidence shows that ducks prioritize access to bathing water over food when given a choice, indicating the strength of this motivation. Best practice duck housing provides swimming areas or at minimum shower systems; some operations have demonstrated that paddling pools requiring daily cleaning can be economically viable. The welfare case for water access in duck farming is one of the clearest examples of a species-specific need that must be met in any acceptable farming system.
