Layer ducks in commercial egg production face the same water access issues as meat ducks, with confined systems frustrating fundamental aquatic bathing and preening behaviors.
Layer duck welfare in confined systems mirrors meat duck welfare challenges - denial of aquatic behavior is a fundamental frustration of species-specific need. Health consequences including eye and nare infections cause direct suffering. The motivation for bathing is so strong that ducks deprived of bathing opportunities show persistent water-seeking behavior at all available water sources, demonstrating that the need is not met by nipple drinkers alone. Addressing layer duck welfare requires the same regulatory attention as laying hen welfare.
