Farmed Laying Hen Perch Design and Welfare

Perch design in cage-free housing affects bone health, keel bone fractures, and resting comfort in laying hens.

Key Facts

Perch use from early life builds bone density through impact loading
Rounded perches of 3-5 cm diameter are recommended for laying hen foot comfort
Perch height and accessibility determine whether all hens can use them
Slippery or sharp-edged perches cause foot lesions and reduce perch use
Falls from high perches contribute to keel bone fractures

Welfare Considerations

Poor perch design creates welfare problems that can negate the intended welfare benefit of providing perches at all. Rounded, appropriately sized perches at accessible heights, combined with non-slip surfaces and ramp access, ensure that perches deliver their bone health and resting benefits for all hens in the flock.

What You Can Do

Support welfare certification specifying perch design standards
Advocate for perch quality requirements in cage-free certification
Choose eggs from farms with evidence-based perch design
