Water access for ducks is a fundamental welfare requirement rooted in physiological necessity, not merely preference or luxury.
Duck water access welfare is both a physiological and behavioural welfare issue. Physiologically, ducks must be able to flush their bills, nares, and eyes with water — this is not a preference but a functional necessity. Ducks deprived of adequate water develop ocular and bill pathologies that cause pain and reduce sensory function. Behaviourally, swimming and bathing are highly motivated behaviours that, when blocked, produce frustration and redirect as stereotypic behaviour. The operational complexity of providing and draining bathing water in commercial duck production is real but not insurmountable — welfare-certified duck producers demonstrate practical management solutions. The welfare case for minimum water immersion access as a regulatory requirement is robust and increasingly reflected in certification scheme standards in European markets.
