Ducks are semi-aquatic birds with strong motivation to access open water, making welfare standards in intensive duck farming a serious concern when water is restricted.
The welfare of intensively farmed ducks is severely compromised by restriction of access to open water. Ducks have evolved to clean their plumage, maintain eye health, and regulate body temperature through water immersion. Deprivation causes measurable welfare indicators including ocular discharge, matted plumage, and high motivation to access water when offered. Higher-welfare duck production systems providing even shallow open-water baths show significant improvements in these welfare indicators.
