Battery Cage Egg Production and the Global Transition

Despite bans in Europe and many US states, barren battery cages remain the dominant system for egg production globally. Over 6 billion hens worldwide live in these severely restrictive conditions.

Key Facts

The EU banned barren battery cages in 2012 - the largest legislative animal welfare advance in history at that time
Enriched cages replaced barren cages in the EU but still provide only 750 cm2 per bird (roughly an A4 sheet)
In non-EU countries including much of Asia, South America and parts of the US, barren cages remain standard
Battery cage hens cannot spread their wings, dust-bathe, nest, perch or perform most natural behaviours
Bone density is severely compromised in caged hens due to lack of movement
Corporate cage-free commitments from major food companies are accelerating the global transition
Better Chicken Commitment signatories represent a significant portion of global egg purchasing

Welfare Considerations

The barren battery cage represents the most extreme example of sacrificing animal welfare for production efficiency. Hens in barren cages experience the full complement of welfare deprivations: confinement, frustration of natural behaviours, bone weakness, and social stress from forced proximity. Progress is real but slow - the EU transition took decades and many countries remain decades behind. Consumer purchasing choices, corporate commitments and policy advocacy remain the most powerful levers for accelerating global cage elimination.

What You Can Do

Buy only cage-free, free-range or pasture-raised eggs
Check restaurant and food service suppliers' egg policies - most still use caged eggs
Support organisations campaigning for corporate cage-free commitments globally
Advocate for cage-free requirements in school, hospital and public sector catering
Reduce egg consumption and choose highest-welfare available when you do purchase
