Laying Hen Enrichment: Perches, Nesting Boxes and Foraging for Better Welfare

Laying hens have strong behavioural needs for perching, nesting and foraging. Meeting these needs is achievable and produces measurable improvements in hen welfare.

Key Facts

Hens have a highly motivated pre-laying nesting drive that causes distress when nesting sites are unavailable.
Perch use reduces keel bone fracture risk by improving bone density and muscle strength.
Foraging behaviour occupies up to 60% of wild jungle fowl waking time — severely restricted in intensive systems.
Providing perches in cage-free systems reduces aggressive pecking by establishing stable spatial hierarchies.
Substrate quality for foraging — depth, composition, moisture — significantly affects use rates.
Litter quality deteriorates rapidly in poorly managed cage-free systems, reducing foraging opportunity.

Welfare Considerations

Laying hen welfare science has documented the motivational strength and welfare significance of nesting, perching and foraging with impressive rigour. Hens show behavioural frustration indicators when these behaviours are prevented and persist in attempting them across a wide range of conditions. Meeting these needs is not merely aspirational but achievable with appropriate system design and management. Enriched environments that provide nesting boxes, perches of appropriate dimensions and deep litter for foraging reduce feather pecking, improve bone health and produce hens with measurably better welfare states. Regular monitoring of enrichment use rates guides management improvements.

What You Can Do

Choose eggs from systems verified to provide nesting boxes, perches and foraging litter.
Support welfare certification that goes beyond basic cage-free to verify enrichment quality.
Advocate for minimum enrichment standards in all laying hen welfare legislation.
Learn about laying hen behaviour science to understand what good welfare requires.
Encourage retailers to share enrichment monitoring data from their egg supply chains.
