Commercial Egg Production: A Welfare Assessment

Commercial egg production involves hundreds of millions of laying hens in systems that vary enormously in welfare outcomes, from deeply problematic conventional cages to higher-welfare free-range systems.

Key Facts

Approximately 8 billion laying hens are kept globally for egg production
Conventional battery cages provide each hen with less space than a sheet of A4 paper
Cage-free systems allow more movement but may have higher rates of pecking injuries without good management
Free-range systems provide outdoor access but access quality varies enormously in practice
Pasture-raised systems with rotational management consistently show the best welfare outcomes

Welfare Considerations

The welfare of laying hens depends critically on housing system, stocking density, breed selection, management quality, and enrichment provision. Even within cage-free systems, poorly managed high-density barns can have worse welfare outcomes than well-managed cage systems. System type matters less than overall management quality in determining individual welfare outcomes.

What You Can Do

Choose pasture-raised or certified higher-welfare eggs
Look beyond labels to understand the specific welfare requirements of certification schemes
Support retailers that publicly commit to higher welfare standards with verification
Reduce egg consumption or use egg alternatives in cooking where possible
Donate to organizations running retailer and food company egg welfare campaigns
