Ducks farmed for meat and down have strong behavioural needs centred on water access. Intensive systems routinely deny these needs, causing chronic frustration and physical welfare problems.
Water is not a luxury for ducks — it is a fundamental biological and behavioural need. Intensive farming systems that deny water access create chronic frustration equivalent to denying rooting substrate to pigs or perches to hens. Eye infections, nasal discharge, and feather degradation in waterless systems are direct welfare consequences of this deprivation. Foie gras production adds acute suffering through forced overfeeding — birds resist the gavage process and develop pathological liver enlargement that impairs normal function. The welfare case against intensive duck farming without water access, and against foie gras production in particular, is among the strongest available for any farmed species.
