Chicken:
Chicken is a kind of poultry. Domestic chicken is derived from wild jungle fowl. Its domestication history is at least about 4000 years, but it was not until around 1800 that chicken and eggs became Mass-produced goods. Types of chicken include turkey, black-bone chicken, pheasant, etc. And the chicken is also one of the 12 zodiac signs.
Our country is the first country in the world to domesticate chickens, with a history of at least four thousand years. Chicken bones or pottery chickens dating back more than 4,000 years have been found in Hubei, Jiangxi, Shandong, Henan, Gansu and other provinces. Chinese chickens were domesticated from pheasants, and there are many excellent varieties, among which Jiujin Huang and Langshan Chicken are very famous. Jiu Jin Huang, also known as Pudong chicken, is produced in Nanhui, Fengxian and Chuansha areas of Shanghai. It is a large broiler chicken with yellow feathers, beak and feet, so it is also called Sanhuang chicken. Jiujin yellow is very large in size and has delicious meat. Therefore, it is welcomed by people all over the world and plays a great role in the improvement of domestic chicken breeds around the world. It was first introduced to Britain in 1843 and to the United States in 1847. The American Rock chicken was created in 1865 by crossing the Chinese Jiujin yellow and the American chicken with black and white spots. Japan introduced Chinese chicken breeds during the Sui Dynasty. By the end of the Tokugawa period, nine-pound yellow chickens from Shanghai were introduced and bred into the famous Nagoya egg-meat chicken. Langshan chicken is mainly produced in Jiangsu area. This kind of chicken has strong disease resistance and well-developed breast meat. Imported to the UK in 1872, the famous British breed of Oppington chicken is a cross between Langshan chicken and local chicken. Later, Langshan Chicken was imported to the United States and Germany. It can be seen that ancient Chinese chicken breeds had a great impact on the world.
