Dustbathing is one of the most fundamental and strongly motivated behaviours of chickens. Its prevention in conventional farming systems is both a significant welfare compromise and an indicator of broader environmental inadequacy.
Dustbathing is a useful welfare indicator precisely because it requires an environmental resource — loose substrate — that is incompatible with the most intensive production systems. Its absence is not a minor inconvenience; it represents chronic frustration of a strongly motivated natural behaviour. The welfare case for provision of appropriate dustbathing substrate is strong, and its inclusion in welfare certification criteria helps translate the science into market signals. For consumers, egg and poultry products from systems that provide genuine dustbathing opportunity represent a meaningful welfare improvement over conventional systems.
