Care and well-being of hens is a top priority for egg farmers.

Hen Care

Egg farmers are committed to quality care and well-being of hens.

Egg Safety

Egg farms participate in many programs to ensure egg safety.


Egg farmers work hard to be responsible stewards of land, water and natural resources.

Disease Prevention

Indoor housing and diligence to biosecurity help protect hens from disease.

What is Cage-Free?

Cage-free eggs are laid by hens that are able to roam vertically and horizontally in indoor houses, and have access to fresh food and water. Cage-free systems vary from farm-to-farm, and can include multi-tier aviaries. They must allow hens to exhibit natural behaviors and include enrichments such as scratch areas, perches and nests. Hens must have access to litter, protection from predators and be able to move in a barn in a manner that promotes bird welfare.

UEP Certified Eggs Show Farm Commitment to Hen Care

Egg farmers are committed to providing the best care possible for their hens. To demonstrate this commitment, United Egg Producers (UEP) developed guidelines for optimal hen well-being – guidelines that are backed by decades of research and recommendations from an independent Scientific Advisory Committee. UEP Certified established guidelines for conventional cage housing in 2002 and for cage-free in 2006.

More than 85 percent of eggs produced in the U.S. come from farms that voluntarily participate in UEP Certified, choosing to open their farms to independent auditors. Eggs from certified farms feature the UEP Certified seal on the egg carton.

About Us

United Egg Producers (UEP) is a cooperative of U.S. egg farmers working collaboratively to address legislative, regulatory and advocacy issues impacting the industry through active farmer-member leadership, a unified voice and partnership across the agriculture community. UEP’s farmer-members work to provide for the health and well-being of their birds; to produce safe, nutritious, high-quality eggs; and to manage their farms responsibly with best on-farm management practices. Leadership of and participation in the UEP Certified program by the vast majority of egg producers further demonstrates a broad commitment to the care of egg-laying hens. UEP also manages the national Egg Safety Center, a leading resource for consumer and industry information on the safe production of eggs and prevention of disease. Formed in 1968, UEP members represent 95 percent of US egg production.

Advisory Committee

Nearly 20 years ago, in 1999, UEP convened an independent, unpaid Scientific Advisory Committee to evaluate egg-laying hen well-being standards, review existing research, conduct new research and recommend changes for egg farms. The first recommendations from this advisory committee became the foundation for UEP Certified. The advisory committee continues today, for ongoing review of new research and modern egg farm standards.
