Hen Welfare in Colony Cage Systems

Colony cage systems for laying hens offer improvements over conventional battery cages but fall short of enriched or free-range systems.

Key Facts

Colony cages provide nest boxes, perches, and scratch areas unlike conventional batteries
Space allowance in colony systems is 600-750 cm2 per bird - still very limited
Hens can perform some natural behaviors but remain severely space-constrained
Colony systems are an industry compromise between welfare and production efficiency
Many welfare organizations advocate moving directly from battery to cage-free systems

Welfare Considerations

Colony cages represent partial welfare improvement over battery cages but do not allow hens to express natural behaviors like dust bathing, ranging, and full wing extension. They are a transitional rather than destination welfare standard.

What You Can Do

Choose free-range or organic eggs over colony cage eggs where available
Support campaigns for full cage-free transitions rather than colony system adoption
Ask retailers about their timelines for moving to fully cage-free sourcing
