Laying Hen Mortality and Welfare in Cage-Free Systems

Transitioning to cage-free laying hen systems improves many welfare outcomes but introduces new challenges that skilled management must address.

Key Facts

Cage-free barn systems show higher mortality rates (3-10%) than conventional cages (2-4%) in many commercial comparisons, primarily from injurious pecking and disease
Well-managed cage-free systems can achieve mortality rates comparable to or below enriched cage systems when enrichment, lighting, and stocking density are optimized
Injurious feather-pecking is the primary cause of elevated mortality in cage-free flocks, linked to frustration, fear, and competition
Providing sufficient nest boxes, perches, litter for dust-bathing, and appropriate lighting significantly reduces pecking behavior
Beak trimming is used to reduce pecking injury risk but is a welfare compromise; enrichment-based prevention is preferable
The Better Chicken Commitment and similar frameworks are beginning to address laying hen welfare alongside broiler welfare

Welfare Considerations

Cage-free systems represent a genuine welfare improvement for laying hens compared to battery or enriched cage systems in terms of behavioral freedom, but the transition requires skilled management to avoid new welfare problems. Poorly managed cage-free systems can produce worse mortality and health outcomes than well-managed enriched colony systems. The welfare dividend of cage-free housing is realized only when stocking density, enrichment, lighting, and stockpersonship are managed correctly.

What You Can Do

Choose eggs from well-managed cage-free, free-range, or pasture-raised systems with welfare certification
Support organizations providing guidance to producers on optimizing cage-free system management
Advocate for welfare auditing standards that verify management quality, not just housing system type
Reduce egg consumption overall while prioritizing highest-welfare certified options
