The Naked Neck is a breed of

dominant one controlled by one gene and is fairly easy to introduce into other breeds,[4] however these are hybrids rather than true Naked Necks, which is a breed recognized by the American Poultry Association since 1965, it was introduced in Britain
in the 1920s. There are other breeds of naked necked chicken, such as the French naked neck, which is often confused with the Transylvanian, and the naked necked gamefowl.

Origin

The origins of the Naked Neck chicken are unclear. A common theory holds that it originated in Asia, where it has long been bred for cockfighting in some countries. It is also depicted in old Japanese paintings.[5] It was eventually introduced to Transylvania (today a part of Romania), where its breeding is documented by the late 19th century.[6] The breed was then introduced to Germany, where it was refined and dispersed to the remainder of Europe and the Americas.[5]

Characteristics

Naked Neck chickens

Despite its highly unusual appearance, the breed is not particularly known as an

eggs, and are considered desirable for meat production because they need less plucking and they have a meaty body. They are very good foragers and are immune to most diseases. The breed is also reasonably cold hardy despite its lack of feathers. Naked Neck roosters carry a single comb
, and the neck and head often become very bright red from increased sun exposure. This breed has approximately half the feathers of other chickens, making it resistant to hot weather and easier to pluck.

Recognized color varieties include: black, white, cuckoo, buff, red, and blue in the United Kingdom[citation needed] and black, white, buff, and red in the United States.[2]

Naked-neck trait

The naked-neck trait which characterizes this breed is controlled by an

true breeding members of the breed must then be homozygous dominant, and all individuals in the recognized breed must be also. Individuals which are homozygous recessive (or wild type feathered) (na+/na+) would not exhibit any feather reduction characteristics of the Naked Necks and, baring mutation, would be unable to pass that trait down.[8]

Scientific studies have indicated that the naked-neck gene (Na) improves breast size and reduces heat stress in chickens of non-

tropical climates if the naked-neck trait (Na) is bred into broiler strains it has been shown to facilitate lower body temperature, increased body weight gain, better feed conversion ratios and carcass traits compared to normally feathered broilers.[10]
