Perch access for laying hens addresses both behavioural needs and bone health - understanding the science guides better housing design and welfare standard requirements.
Perch welfare for laying hens combines behavioural and physical health dimensions. The behavioural motivation to perch is strong - hens denied perching show frustration and sleep at ground level in huddled groups showing the importance of elevated roosting. The physical benefit of bone loading through perch use directly reduces osteoporosis and keel bone fracture risk. Perch design matters: diameter, height, material and stability all affect willingness to use available perches. Welfare standards specifying perch provision should include quality requirements not just availability. The combination of behavioural and physical health benefits makes perch provision one of the most welfare-positive investments in laying hen housing.
