Three-egg brands are generally larger vertically integrated operations and/or purchase eggs from multiple farmers (or work with farmers on a contract basis supplying the chickens, feed and management oversight). Based on our analysis they appear to all meet the minimum USDA standards for legal outdoor access and many deserve credit for being fully transparent with Cornucopia researchers, and indirectly their organic community customers (Note: please see score on disclosure rate below – the score on this question also relates to their willingness to have their farms open to our inspection and/or supply required photographs of all four sides of each chicken coop producing their eggs). We've invited them to write a bit about their farm and operation...

PLEASE NOTE: this is the listing for Great Valley's regular organic eggs. Their pastured eggs have a separate listing.

Looking for a way to bring his family up in the country, away from the city, George Jenkins purchased a small chicken ranch in the Central San Joaquin Valley in 1967. Needing a business partner he turned to his father-in-law, Chester McKim. On this ranch they raised chickens and provided eggs to a small processor in Ripon, California. Seeing the need for cage free and organic grown chickens he converted the farm to completely cage free in 1995. Great Valley Poultry has been organic certified with Global Culture since 2004. Now his daughter, Dana Corbin and her husband, Arney Corbin have taken over the farm and still believe in the need for cage free and organic eggs. Their son Denton Corbin is currently enrolled at the local Junior College majoring in Poultry Science and Ag Business. This makes the farm a four generation farm and still going strong
