Hen Bone Health: Osteoporosis Prevention in Laying Flocks

Osteoporosis and bone fractures are endemic in commercial laying hen populations, causing widespread chronic pain.

Key Facts

Over 50% of laying hens have at least one fractured bone during their productive life
Medullary bone depletion from calcium transfer to eggshell drives bone weakness
Access to perches and exercise significantly improves bone strength
Higher welfare systems with exercise space show lower fracture rates

Welfare Considerations

Bone fractures cause acute and chronic pain in laying hens. The scale of this problem - affecting millions of birds - makes it one of the most significant welfare issues in farm animal production. Perch access and exercise are proven preventions.

What You Can Do

Choose eggs from cage-free or free-range systems with verified perch access
Support research into lower lay-rate breeds with improved bone health
Advocate for mandatory perch provision and exercise space in all laying systems
