Ducks are aquatic birds whose welfare is significantly compromised in commercial systems that provide only nipple drinkers without meaningful water access for bathing and splashing.
Denying aquatic birds access to water for bathing represents a fundamental frustration of species-specific behavior. Ducks without bathing water develop plumage soiling, eye and nare problems, and show persistent water-seeking behavior indicating unmet need. The welfare gap between US and EU standards is particularly pronounced for ducks. Providing even simple open water troughs or sprinklers significantly improves welfare at modest cost, suggesting economic considerations rather than technical limitations drive current US practices.
