Chicken Behaviour and the Case for Enriched Environments

Chickens are highly motivated to perform a range of natural behaviours including dust bathing, perching, foraging, and ranging. Understanding these motivations strengthens the case for enriched housing.

Key Facts

Hens deprived of dust bathing substrates perform vacuum dust bathing — the behaviour on bare floors without dust
Perching at night is a strong evolved behaviour linked to predator avoidance — hens without perches show elevated cortisol
Foraging motivation is so strong that hens prefer to work for food even when food is freely available (contrafreeloading)
Hens given outdoor access typically use it selectively — enriched vegetation areas are strongly preferred to bare paddocks
Visual barriers in free-range systems dramatically increase range use by reducing predator vigilance costs

Welfare Considerations

Chicken behaviour science has transformed our understanding of what hens need beyond physical health. Dust bathing, perching, foraging, and range use are not optional luxuries — they are behaviours hens are strongly motivated to perform and experience reduced welfare when prevented from doing so. Enriched housing that provides substrate for dust bathing, perches at appropriate heights, foraging opportunities, and stimulating outdoor access with vegetation and visual barriers meets these needs at reasonable cost. Consumer demand for higher welfare eggs and chicken is the most effective driver of adoption.

What You Can Do

Choose eggs and chicken from systems that provide dust bathing substrate, perches, and outdoor enrichment
Support supermarkets and food service companies that have committed to the Better Chicken Commitment
Advocate for enrichment requirements in commercial poultry housing standards and certification schemes
Share chicken behaviour science to build public understanding of what welfare means for farmed birds
