The design of perches in laying hen housing significantly affects their welfare and keel bone fracture rates.
Perch design is a welfare detail with significant consequences. Perches that are too thin, too high, too close together, or made of inappropriate materials increase keel bone fracture rates and foot sores. Hens cannot always land precisely on perches in crowded conditions — the injury risk from collision with perch edges and falls is real. The best perch designs allow gradual approach through staggered heights, provide adequate grip, and are positioned to allow hens to see and approach safely.
