In one case, there may be a chicken with many wings and gene mutation, but such a situation can not be met, and under such a premise, whether this chicken can hatch smoothly is a problem, let alone offspring.
In fact, if we start from the technical aspect, there are two ways to achieve this goal. The first is in vitro transplantation, that is, transplanting the wings of one chicken to another chicken. If this method is adopted, the result that a chicken has multiple wings is that other chickens have no wings.
The second method is embryo transfer. It is feasible to induce embryonic stem cells to differentiate into extra chicken wings, but the cost is very high.
Therefore, it is feasible to cultivate multi-wings in chickens. However, if the case is put back to the KFC incident, neither of these two methods can be realized. The first method, for KFC, the total number of chicken wings has not changed at all, so don't bother; The second method is too expensive to be adopted!
Chicken raising history
China is the first country in the world to domesticate chickens, with a history of at least 4,000 years. In Hubei, Jiangxi, Shandong, Henan, Gansu and other provinces, there are chicken bones or pottery chickens more than 4000 years ago.
Chicken raising in China is domesticated by pheasants, and there are many excellent varieties, among which Huang and Langshan chickens are very famous. Huang, also known as Pudong Chicken, is a large broiler with yellow feathers, beak and feet, so it is also called Sanhuang Chicken.
Nine catties of yellow, particularly large, delicious meat, so it is welcomed by people all over the world, and has played a great role in the improvement of domestic chicken varieties in the world. 1843 was first introduced to Britain, and 1847 was introduced to the United States. American Rock Chicken is a hybrid of nine catties of yellow and 1865 black and white American chicken from China.
The Japanese introduced China chicken in the Sui Dynasty, and at the end of the shogunate, they introduced nine catties of Shanghai yellow chicken to cultivate the famous Nagoya egg and meat chicken. Langshan chicken is mainly produced in Jiangsu, with strong disease resistance and developed breast chicken.
1872 was introduced into Britain, and the famous British breed, Opington Chicken, was made by crossing Langshan Chicken with local chicken. Later, Langshan chicken was imported to the United States and Germany. It can be seen that the domestic chicken breeds in ancient China have great influence on the world.
