Perch access is a fundamental welfare requirement for laying hens. The ability to roost at height satisfies strong natural motivations, reduces social aggression, and improves psychological wellbeing.
Perch access is not a welfare luxury — it addresses a deep-seated behavioural need rooted in millions of years of evolutionary pressure to sleep off the ground. Hens deprived of perching experience frustration, disrupted sleep patterns, and increased social conflict. The welfare gap between systems offering meaningful perch access and those offering none or inadequate provision is substantial. Perch design matters too: rounded perches of appropriate diameter (3-4cm) in positions that allow natural roosting posture provide better welfare than narrow, flat, or inappropriately placed alternatives. Consumer and retailer pressure for meaningful enriched cage and cage-free standards should include specific attention to perch provision quality.
