Artificial cultivars are long-term breeding in South Africa using hybrids such as blue-necked ostriches. African black ostriches are smaller in size, short in legs, plump in body, docile in temperament, dense in feathers, evenly distributed, and have long feathered twigs that look very beautiful and are easy to feed and manage. Its egg production performance is better than that of blue-necked and red-necked ostriches. Generally, the average female egg-laying 25-year-old hens produces 34 eggs per year, with up to 50 excellent ones. China Agricultural Network Editor
