Egg production welfare depends heavily on housing system. Understanding the welfare differences between conventional cages, cage-free, free-range, and pasture-raised systems helps consumers choose meaningfully.
Housing system is the single largest determinant of laying hen welfare outcomes. Battery cages cause profound behavioral deprivation — hens cannot spread wings, dustbathe, perch, or nest. Bone fractures from calcium depletion and immobility are near-universal. Cage-free systems provide dramatically better outcomes for behavior and bone health but require careful management to prevent the injurious pecking that emerges in large flocks. Pasture systems — particularly Certified Humane Pasture Raised — provide the best welfare outcomes, allowing expression of the full behavioral repertoire including foraging, dustbathing, and social behavior in natural light and space. The price premium for pasture eggs reflects genuine production cost differences, not just marketing.
