The study was carried out on Minh Du Poultry Breeding Limited Company, Huynh Mai, Phuoc Nghia, Tuy Phuoc, Binh Dinh. The objective is to assess phenotypic characterisation and grow ability as well as meat performance of MD1.BĐ, MD2.BĐ, MD3.BĐ chicken. A number of 300 chicken/crossbreed with 3 repeatations was observed. The results showed that at 13 weeks of age, the feather colour of MD1.BĐ and MD2.BĐ and MD3.BĐ cook were black red.
