Stocking density in commercial duck production strongly influences welfare outcomes, affecting locomotion, water access, feather condition, and social behavior.
Ducks are semi-aquatic birds with strong behavioral motivation to swim, bathe, and forage in water. Commercial duck farming that denies water access frustrates these fundamental behavioral needs, causing chronic welfare compromise. Studies show ducks prioritize water access for bathing even when water for drinking is available, demonstrating the strength of this need. Foie gras production represents an extreme welfare violation that has been banned in many jurisdictions. Welfare standards for ducks lag significantly behind those for chickens and pigs.
