The Hidden Welfare Costs of Cheap Eggs

The cheapest eggs in the supermarket represent the worst welfare outcomes for laying hens globally.

Key Facts

Conventional battery cage hens have approximately 67 square inches of living space each
Hens in battery cages cannot spread their wings, dust bathe, or perform any natural behavior
Cage-free systems provide more space but still require rigorous management to be welfare-positive
The price difference between conventional and highest-welfare eggs is typically 50-100%

Welfare Considerations

The low price of conventional eggs reflects the externalization of animal welfare costs onto hens. Battery cages provide a living space smaller than a sheet of paper for each bird — conditions that prevent every natural behavior and cause chronic stress and frustration. The welfare improvement trajectory from battery cages through enriched cages, cage-free systems, and aviary systems with outdoor access is real and measurable. Choosing the highest welfare eggs available within budget, or reducing egg consumption, are both meaningful welfare actions.

What You Can Do

Avoid conventional battery cage eggs entirely
Choose the highest welfare certification available within your budget
Reduce egg consumption to lower demand from intensive production
Advocate for cage-free requirements in public procurement and institutional catering
