Welfare outcomes for laying hens vary substantially across production systems from conventional cages to free-range and organic, with evidence guiding consumers toward better choices.
Welfare evidence across egg production systems is nuanced but directional. Conventional battery cages cause the greatest suffering through extreme movement restriction. Enriched cages add nest boxes and perches — marginal improvements but substantial in their effect on behavioral freedom. Free-range systems enable dust bathing, foraging, and movement but create disease pressures and can lead to high mortality. Organic and high-welfare free-range systems with lower stocking densities and good management consistently produce the best welfare outcomes across most measured dimensions.
