The Naked Neck chicken, colloquially nicknamed the "turkey chicken," features a naturally featherless neck that mimics a turkey's appearance. Far from being a sign of illness, this distinctive trait is driven by a single dominant gene called the "Na gene," which actively inhibits feather development along the neck area from the time the chick hatches.
From an evolutionary perspective, this lack of plumage provides a distinct advantage by allowing the bird's exposed skin to dissipate body heat rapidly. This makes the breed far more heat-tolerant than typical poultry, and they generally carry 20 to 30 percent fewer feathers across their entire bodies than standard chickens.
Due to this unique biological adaptation, Naked Neck chickens are incredibly popular in tropical climates. Breeders frequently utilize them to crossbreed and introduce superior heat resistance into other poultry strains, allowing farms to manage hotter environments more effectively.
