Intensive Egg Production: Transition to Cage-Free

The global transition from battery cages to cage-free egg production is accelerating, driven by corporate commitments and legislation. Understanding what cage-free really means for welfare is essential.

Key Facts

Battery cages — providing 67cm2 per hen — are banned in the EU and many US states
Cage-free systems allow hens to move, spread wings, and access nest boxes and perches
Cage-free does not mean outdoor access — that requires free-range or pasture certification
Cage-free system welfare depends heavily on management, stocking density, and enrichment quality
Over 2,000 major food companies have made cage-free commitments as of 2023

Welfare Considerations

The cage-free transition is one of the largest welfare reforms in farm animal history, affecting hundreds of millions of hens globally. Cage-free systems represent a genuine and significant improvement over battery cages for most welfare measures. However, cage-free is not a uniform welfare standard — poorly managed cage-free systems with inadequate enrichment, high stocking density, and poor litter quality can cause significant welfare problems including dust bathing deprivation and keel bone fractures. High-quality cage-free management is the essential complement to the system transition.

What You Can Do

Support cage-free commitments from food companies and demand accountability on timelines
Choose eggs certified by third-party welfare auditors beyond just cage-free labeling
Advocate for cage-free standards that include enrichment and stocking density requirements
Ask retailers when they expect to complete their cage-free transitions
Consider reducing egg consumption or using plant-based alternatives as cage-free transitions proceed
