The housing system for laying hens has profound welfare implications. Understanding the differences between cage, barn, and free-range systems helps consumers make informed choices.
Keel bone fractures — caused by collision with cage furniture, perch falls, or bone fragility from high egg production — are the most prevalent welfare problem in laying hens. They cause persistent pain that manifests in altered posture, reduced activity, and lower production. Enriched cages, despite improvements over battery cages, still prevent many natural behaviours including wing-spreading, dust bathing, and full expression of social hierarchies. Free-range and organic systems enable more natural behaviour but introduce new challenges including smothering, aerial predators, and feather pecking in large flocks. Higher-welfare systems consistently produce better welfare outcomes when managed well.
