Four Generations

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.

Straight from the Farms to Your Plates!

The eggs are sold directly from our farm to the customer at the farmers market. We process and package all the eggs right out of the chicken house. They could not be any fresher! We practice sustainable farming and reuse and reduce all waste at the farm level.

We maintain small bird numbers in each flock to give personal attention to every flock on the ranch. Our organic birds are allowed to wander out of the house each day to stretch their wings and give them a chance to enjoy the fresh California air. We are fully licensed by the California Department of Food and Agriculture and inspected each year by our county agriculture department and our organic certifier, Global Culture. We maintain a strict quality assurance program to make sure you are provided with healthy eggs. We are also registered with the FDA.   

Our organic pastured birds have 24 hour access to some of the finest organic pasture in the San Joaquin Valley. They are free to roam as they choose.  This gives our pasture the best fertilizer nature has to offer. These birds are fed organic feed and free from GMO's.

All of our hens are also offered a nutritious corn blend feed that ensures you are getting a great tasting and nutritious egg.  Our feed consists of corn, small amounts of soybean meal and just enough essential amino acids and lysine to ensure our hens are eating the right stuff to keep laying eggs to deliver to
your family.

Our farms is also certified humane through Humane Farm Animal Care so you know our birds are
treated well.

Our number one priority is to keep all of our chickens healthy!
