The California Gray is an American breed of domestic chicken. It was developed in California in the 1930s by Horace Dryden in Modesto, California.[4]: 432 His aim was to produce a dual-purpose chicken that was both suitable for meat production and laid large white eggs. By crossing a Barred Plymouth Rock rooster and a White Leghorn hen, a naturally autosexing breed with gray barred plumage (as adults) was produced. Largely because the breed was never recognized officially for exhibition by the American Poultry Association, The California Gray is a rare breed in the twenty-first century.[2] It is not listed on the conservation priority list of the Livestock Conservancy.[5]
California Gray cocks are crossed with White Leghorn hens to produce the California White commercial sex-link hybrid, and may be known as "production black".[1]
