Beak trimming of ducks in intensive farming systems raises welfare concerns, with feather-pecking the behavior it aims to prevent.
Duck bill trimming causes pain and affects feeding behavior — ducks rely on their highly sensitive, lamella-lined bills to filter food from water, and trimming disrupts this natural feeding mechanism. Feather-pecking, the behavior it aims to prevent, is itself a welfare indicator of inadequate environment. Rather than modifying animals to fit poor environments, evidence supports addressing the underlying causes: overcrowding, inadequate water access for bathing (essential for ducks), poor lighting, and social stress. Providing ducks with open water access for bathing and foraging, even in partial capacity, dramatically reduces stereotypic and injurious behaviors.
