The EU battery cage ban has generated important lessons about the pace, politics, and practical challenges of large-scale farm animal welfare reform.
The EU battery cage ban is both a welfare success and a lesson in reform limitations. Eliminating the worst form of caging for 300 million hens represented a genuine welfare advance. But the replacement -- enriched cages with slightly more space, a perch, and a scratch mat -- still falls well short of what welfare science identifies as adequate for hens. The ban was followed by persistent non-compliance in some countries and a decade of enriched cage production that critics argue merely made intensive confinement marginally more defensible. True welfare progress requires moving beyond enriched cages to genuine free-range or higher-welfare systems -- a transition happening unevenly through corporate commitments rather than regulation.
