Ducks have strong motivation to access water for bathing, swimming, and feeding behaviour that intensive farming often fails to provide.
Duck welfare in intensive farming is compromised by the mismatch between the species' strong water-related behavioural motivations and the barren, dry environments typical of commercial production. Ducks denied bathing water show persistent attempts to fulfil the behaviour using available nipple drinkers, demonstrate frustration behaviours, and suffer impaired eye and feather hygiene. Higher-welfare systems provide bathing water through troughs, ponds, or sprinkler systems — meaningful improvements that significantly improve welfare indicators. Foie gras production represents the most extreme welfare abuse in duck farming, causing pain, respiratory distress, and organ failure through forced overfeeding.
