Ducks have highly specialised sensory anatomy and strong water-use behaviours that are severely compromised in most commercial duck production systems. Understanding their specific needs drives better welfare standards.
Duck welfare in commercial systems is profoundly affected by the near-universal absence of open water access. Ducks evolved to spend large portions of their active time in water — foraging, cleaning, bathing, and displaying socially. Nipple drinkers meet hydration needs but deny bill immersion, head washing, eye irrigation, and aquatic locomotion. Ducks without open water access show abnormal bill-wiping behaviour, increased incidence of eye discharge and infection, and frustrated aquatic locomotion attempts. Bill sensitivity means that trimming performed in some systems causes acute and potentially chronic pain affecting feeding behaviour. The welfare gap between what commercial duck production provides and what duck biology requires is wide; the UK standard of head-immersion-capable water access represents a minimum that most countries have not adopted.
