Range Design for Laying Hens and Welfare

The design of outdoor range areas determines whether free-range hens actually benefit from outdoor access.

Key Facts

Up to 40% of free-range hens never venture beyond 10 metres from the house
Trees, shrubs, and artificial shelters on range increase usage by 30-60%
Hens prefer range areas with overhead cover that protects from aerial predators
Rotation of range areas prevents parasite build-up and maintains sward quality
Water points and shade structures distributed across the range increase engagement

Welfare Considerations

Free-range egg production delivers welfare benefits only if hens actually use the range. Range reluctance — the phenomenon of most hens staying close to the house — means that millions of nominally free-range hens gain little benefit from outdoor access. Evidence shows that range design is the primary determinant of usage. Trees and shrubs provide cover against perceived aerial predator threat that prevents hens from venturing far from the house. Range design should be considered as integral to free-range welfare as the outdoor access itself.

What You Can Do

Choose eggs from producers with demonstrably good range design rather than just access
Support certification schemes with range design and usage requirements
Learn about the welfare evidence for range design and its effects on hen behaviour
Advocate for range design standards in free-range certification requirements
Plant trees or shrubs in any small-scale free-range poultry area to encourage range use
