Ducks are waterfowl with strong motivational needs to bathe, preen with water, and dip their bills. Most commercial duck production denies these needs, causing chronic frustration and welfare harm.
Denying ducks access to open water is a significant welfare harm. The motivation to bathe is strong enough that ducks deprived of water develop eye and nasal discharge, feather condition problems, and behavioral frustration. Provision of even a small open water trough represents a meaningful welfare improvement. Full bathing facilities allow normal preening, bill health maintenance, and thermoregulation.
