  The California Gray is an American breed of domestic chicken. It may be also known as the "production $black".^{:47}$
  
  ## History
  
  The California Gray was developed in California in the 1930s by Horace Dryden in Modesto, $California.^{:432}$ His aim was to produce a dual-purpose chicken that would be suitable for meat production and would also lay large white eggs. By cross-breeding of Barred Plymouth Rock and White Leghorn birds, an autosexing breed with barred gray adult plumage was produced. As in other autosexing breeds, the sex of chicks can be distinguished at about a day $old.^{:47}$
  
  The California Gray was never recognized as a breed by the American Poultry Association, and in the twenty-first century is a rare $breed.^{:47}$ It is not listed on the conservation priority list of the Livestock Conservancy, and is not reported to the DAD-IS database of the FAO.
  
  ## Use
  
  The California Gray is a dual-purpose bird, producing both meat and eggs. Cocks are crossed with White Leghorn hens to produce the California White commercial sex-link $hybrid.^{:47}$
