Battery Cage Eggs and Global Transition

The global transition away from battery cage egg production is uneven, with rapid progress in some markets and stagnation in others.

Key Facts

The EU banned conventional battery cages in 2012; California, Massachusetts, and several US states have follow-up bans
Global battery cage use remains dominant in Asia, Africa, and parts of Latin America — over 5 billion hens affected
Retailer commitments to cage-free eggs have driven faster transition than legislation in the US and Australia
Cage-free systems require more complex management but show better behavioral welfare outcomes for key indicators
The International Finance Corporation has adopted cage-free standards for egg project financing globally

Welfare Considerations

The battery cage welfare harm — hens unable to stand, spread wings, or express any natural behavior — is well-established and the transition technology exists. The pace of change is primarily determined by regulatory and market pressure. International finance institutions, corporate supply chain commitments, and consumer demand are all tools for accelerating transition in markets where legislation has not yet acted.
