Jersey Giant Chicken Breed Details and Management Information

The Jersey Giant, as the name suggests is one of the largest chicken breeds in the world. When you encounter one, you will probably never forget it. 

Though the popularity had gone down, due to its poor feed to weight conversion ratio, the Jersey Giant is becoming popular among backyard poultry keepers.  The poor feed to weight conversion ratio is due to the fact that Jersey Giants develop the frame first, then starts building on the flesh after 6 months. 

With cocks weighing 13 pounds and hens 10 pounds, it is a good choice for the backyard poultry keeper because of its meat yield and egg production.

History of the Jersey Giant Chicken Breed

Bred to meet the need for heavy roasting chickens, the Jersy Giant was developed from crosses of Black Javas, Orpingtons, and Black Langshans. They were originally named Jersey Black Giants, after the Black brothers (Thomas and John) who bred them in New Jersey. 

It was bred to compete with the common turkey, in terms of big roasting meat potions. At the time there was demand for large capons for the roasting markets of New York, Philadelphia, and Boston

The introduction of the broad-breasted turkeys later in the development of Jersey Giant caused it not to become popular since the broad-breasted turkeys filled the market niche the Jersey Giant was being developed for. 

The breeders of the Jersey Giant never paid attention to the colors. A breeder by then name Maloney saw the need to standardize the color. His work came up with the black Jersey Giant. 

The white Jersey Giant came up as a sport (Mutation) of the black Jersey Giant. The blue Jersey Giant was developed later in the 20th century. 

The Bantam variety of the Jersey Giants has also been developed.
