Enrichment for Laying Hens: Evidence and Practice

Environmental enrichment for laying hens addresses behavioural needs and reduces welfare problems including feather pecking and boredom.

Key Facts

Pecking objects like hanging strings and chains provide manipulable enrichment for laying hens
Perches significantly reduce bone fragility in laying hens by maintaining muscle and bone loading
Dust bathing is one of the most strongly motivated behaviours in laying hens requiring substrate provision
Beak trimming reduces pecking but addressing enrichment needs is preferable as a root cause solution
Complexity in the environment reduces uniformity that drives redirected pecking behaviours

Welfare Considerations

Laying hen enrichment addresses the gap between what hens are motivated to do and what barren housing systems allow them to do. Pecking, scratching, dust bathing, perching and nesting are not optional extras but fundamental behaviours driven by strong internal motivation. Hens in barren environments redirect these motivations toward cage mates, causing feather pecking and injury. Enrichment that provides appropriate outlets for these behaviours prevents feather pecking more effectively than beak trimming, which suppresses the behaviour without addressing the motivational deficit.

What You Can Do

Support certification schemes requiring meaningful enrichment provision for laying hens
Advocate for dust bathing substrate, perches and pecking objects as minimum requirements
Choose eggs from systems providing genuine behavioural enrichment rather than minimum compliance
Support research into cost-effective enrichment solutions for large commercial laying hen flocks
