Dustbathing Behaviour and Laying Hen Welfare

Dustbathing is a highly motivated behaviour in laying hens that is frustrated by conventional cage and floor housing.

Key Facts

Hens dustbathe for 15-30 minutes daily to maintain feather and skin condition
The behaviour is so strongly motivated that hens perform sham dustbathing on wire floors with no substrate
Dustbathing involves wing-shaking, rolling in substrate, and bill-raking — requiring space and suitable material
Conventional cages physically prevent dustbathing causing chronic frustration
Free-range hens with access to dry soil dustbathe multiple times daily

Welfare Considerations

Dustbathing is not a luxury for laying hens — it is a fundamental behaviour as motivated as feeding and drinking. Hens deprived of dustbathing opportunities show significant signs of behavioural frustration. Providing dustbathing substrate — ideally sand, peat, or fine litter — in a dedicated area of the enclosure allows hens to perform this behaviour fully and reduces stress. The provision of dustbathing material is a welfare improvement that dramatically improves quality of life at minimal cost.
