John and Thomas Black developed the Jersey Giant in nineteenth-century New Jersey. Their project sought a very large table chicken and drew on Java, Langshan and Brahma ancestry.
The Black brothers developed the birds from 1870 to 1890 near Jobstown, New Jersey, hoping for a table chicken that could compete with turkeys. American standard recognition followed for Black in 1922, White in 1947 and Blue in 2003.
Jersey Giants have a large, broad frame, clean legs and a single comb. Black birds show green sheen and yellow foot soles. The Conservancy reports mature males around 13–15 pounds and females around 10–11 pounds, distinct from lower market-weight figures. Their size is paired with a generally calm disposition.
A breeder's account of developing Blue Jersey Giants
Golda Miller, a former National Jersey Giant Club president, described the development of her Blue Giants in a 1998 breeder article. She recalled an unusual White hen with gray feathers and the decision to lend that bird to Leo Prokop. The first offspring were varied in color; further mating with a Black male produced more promising birds, after which Miller brought the original hen and some descendants home.
The account is valuable primary testimony about one breeder's stock and sequence of decisions. It also rejects the idea that simply crossing any White Giant with any Black Giant will reliably create Blue Giants. White appearance can conceal different underlying genetic situations, so color labels alone are an inadequate breeding recipe. Miller's observations explain her line's development; they do not establish that every Blue Giant descends from that particular hen or provide a complete molecular explanation.
