Farmed ducks face welfare problems ranging from water deprivation in intensive systems to the extreme suffering of force-feeding in foie gras production.
The most acute welfare failure in duck farming is water deprivation. Ducks have waterproof plumage, specialised bill structures, and behaviours — head dipping, swimming, bathing — that are fundamental to their nature. Without open water, they cannot keep eyes and nostrils clean, causing chronic eye and respiratory irritation. Foie gras production represents an extreme welfare harm: force-feeding induces hepatic steatosis so severe the liver can enlarge to 10 times normal size, causing difficulty breathing, walking, and metabolic distress. Scientific bodies including EFSA have concluded that current foie gras production methods necessarily cause suffering that cannot be mitigated without ending the practice.
