What makes an egg “legal”?
A plain-language, sourced guide to the rules behind the carton: who defines cage-free, free-range and pasture-raised, which US states ban the sale of eggs from caged hens, and how Europe’s 2012 battery-cage ban played out.
US state cage-free lawsCalifornia, Massachusetts, Washington, Oregon, Colorado, Michigan, Nevada, Arizona, Utah and Rhode Island — with dates and status.

Key points for US shoppers
- Federal law does not ban cages. Hen-housing rules in the US come from state laws and ballot measures. Ten states have adopted laying-hen confinement laws, according to the ASPCA’s state tracker; several of them also ban the sale of non-compliant eggs, wherever they were produced.
- “Cage-free” and “free-range” have USDA meanings — on graded cartons. The USDA Agricultural Marketing Service verifies these claims on cartons that carry the USDA grade shield. Its April 2025 policy memo says free-range hens must have “continuous access to outdoors during their laying cycle”; cage-free hens must be able to roam indoors but need no outdoor access.
- “Pasture-raised” has no single federal definition. On USDA-graded cartons it must be backed by a third-party certifier such as Certified Humane or American Humane.
- Safety rules are separate from welfare claims. The FDA’s Egg Safety Rule and the “Safe Handling Instructions” statement apply to eggs regardless of housing system (FDA).
Where the name comes from
This domain was used in 2012 for a UK campaign in which members of the public pledged support for keeping eggs from cages made illegal by an EU directive out of the UK. That campaign has no connection with this site. Its history is summarized, in the past tense and with sources, on the pledge history page; the underlying law is on the EU legislation page.
