A rare Vietnamese chicken breed called the Dong Tao, prized for its delicious meat, has one of the most thickest legs usually not seen among birds of that size. This chicken breed is endemic to the Dong Tao commune in Khoai Chau district, about 30km from Hanoi. Once bred exclusively to serve the royal family and mandarins, this rare breed is now prized by chicken breeders and its meat is served in expensive restaurants that cater to the wealthy. The legs themselves are a delicacy.
