Ducks are farmed primarily for meat and liver, but their strong behavioral need for water access is rarely met in intensive production systems.
Ducks have evolved as water birds with feather structures maintained by water immersion. Without access to bathing water, ducks cannot clean their plumage or eyes normally, leading to eye infections, feather deterioration, and frustration. Research shows that bathing water is among the highest-priority resources for ducks, measured by their willingness to work to access it. Despite this evidence, most commercial duck production provides only drinking nipples or cups. The UK passed regulations requiring ducks in commercial production to have access to open water for bathing, a significant welfare improvement. Foie gras production of duck liver through force-feeding is banned in the UK, Germany, Netherlands, and other countries.
