Intensive Egg Production and Hen Welfare Reform

Battery cage hens have been a symbol of intensive farming welfare harms, driving global reform movements toward cage-free and enriched cage systems.

Key Facts

Battery cages were used to house over 90% of US laying hens at their peak
California Proposition 12 (2018) requires cage-free housing for in-state egg sales
The EU phased out conventional battery cages in 2012
Cage-free systems allow natural behaviors but can have higher mortality from pecking
Enriched colony cages provide perches, nesting boxes, and scratching pads but remain controversial

Welfare Considerations

Battery cage abolition represents one of the most significant farm animal welfare policy achievements of recent decades. However, the successor systems involve their own welfare trade-offs. Cage-free systems reduce restriction but increase risk of disease spread and pecking injuries. Truly high welfare outcomes require low stocking densities, outdoor access, and complete behavioral freedom.

What You Can Do

Choose pasture-raised eggs with the highest welfare standards and outdoor access
Support legislation requiring cage-free minimum standards as a floor not a ceiling
Advocate for low stocking density standards in cage-free egg production regulations
Reduce egg consumption to lower demand pressure on all production systems
Support welfare organizations campaigning for comprehensive laying hen welfare standards
