Dust bathing is essential for poultry welfare across species, but adequate provision requires attention to substrate, space, and timing.
The welfare goal is not merely the presence of a dust bathing area but genuine behavioral satisfaction of the motivation. A single dust bath area for 500 hens cannot satisfy all birds simultaneously. Substrate that becomes wet and unusable fails to meet the need. The correlation between adequate dust bathing provision and reduced feather pecking demonstrates the behavioral significance of meeting this need.
