The California Gray was developed around 1930 by Professor James Dryden. The goal was a dual-purpose breed that laid large white eggs, as that was what the market wanted at that time. And he was also striving for a bird that would lay well for more than 2 years. The birds have a body type heavier than a Leghorn but not as "clunky" as a Rock. Unlike most of the white egg breeds, Grays are not flighty birds and are excellent winter layers in cold climates.
