Laying Hen Welfare: Cage-Free Progress and Challenges

The global transition from battery cages to cage-free laying hen systems is underway, but cage-free does not automatically mean high welfare. Understanding the nuances drives better choices.

Key Facts

Approximately 6 billion laying hens are kept globally — most in battery or enriched cage systems
Battery cages — which give each hen less space than an A4 sheet of paper — are banned in the EU but still legal in most countries
Enriched cages allow slightly more space but still prevent many natural behaviours including dust bathing and wing spreading
Cage-free barns allow more movement but can have high stocking densities and poor air quality without good management
Free-range hens have outdoor access but may rarely use it if range quality and cover are inadequate
Feather pecking and cannibalism in cage-free flocks are welfare challenges requiring management solutions

Welfare Considerations

Cage-free is a welfare improvement over battery cages — but it is not the end of the welfare story. In poorly managed cage-free barns, hens can face crowding, poor air quality, high ammonia levels, and severe feather pecking that causes injury and death. The welfare gains of cage-free systems are real and meaningful, but they must be accompanied by appropriate stocking densities, environmental enrichment (perches, litter, dust baths, nesting boxes), good stockmanship, and breed selection that reduces feather pecking. The welfare ceiling in a well-managed free-range or organic system far exceeds that of even the best cage system.

What You Can Do

Choose eggs labelled free-range, organic, or RSPCA Assured over cage-free or cage eggs
Ask supermarkets and food service companies about their cage-free transition timelines
Support companies that have committed to and met 100% cage-free supply chain targets
Share cage-free progress tracking tools like the Egg Track platform with food industry contacts
Reduce egg consumption and explore plant-based egg alternatives where possible
