Noi chickens raising in surveyed areas had a variation of morphological traits with red, black, cinereous feather color for male chickens and brown for female chickens. Noi chickens had a great performance with sale weight from 1.5-1.9kg at 120-180 days old. Besides, the use of disease prevention methods and vaccination process was not applied in a good way.
