Embodiment 1

[0019] Step 1. Introduce 2,000 purebred Dongxiang black-feathered green-shell hens for adaptive purification and breeding, and select and retain 400 hens as female parents; introduce 2,000 purebred Taihe silky chickens for adaptive purification and breeding, Select and retain 50 roosters as male parents, and crossbreed to produce the F1 generation. The feathers of the F1 generation are black feathers, and the black traits are separated in different degrees; the selection is carried out according to the selection criteria that the feathers are all black, black characteristic traits such as skin, bones, meat, and internal organs, and the beak, tongue, anus, and shin are all black. At the same time, compare the black color of the black characteristic traits, and give priority to the darker black individuals to save seeds; the traits such as bones, meat, and internal organs are determined by siblings and family selection methods, and the traits such as skin, beak, tongue, anus, and...
