Free-range egg certification requires outdoor access, but the welfare benefit depends critically on whether hens actually use the range. Understanding the barriers to range use helps improve real-world welfare outcomes.
Free-range labelling does not automatically deliver welfare benefits; the gap between range availability and actual range use means that many certified free-range hens have similar day-to-day lives to housed counterparts. Hens that use the range benefit through exercise, UV light exposure, natural foraging behaviour, and reduced inter-individual competition in the house. Hens that do not venture outside miss these benefits. The barriers to range use — predator risk, lack of cover, social crowding at pop-holes — are manageable through better range design. Vegetation planting close to exits, artificial shelter structures, and predator deterrents significantly increase range use and thus the welfare value actually delivered. Measuring range use as a welfare outcome — not just providing access — is the more meaningful certification standard.
