First, the rooster can be used as a kind of chicken. First of all, we should know about roosters. Although it is rare in our daily life, raising chickens in rural areas still needs to be cracked down. In the vast rural areas of China, we still use indigenous methods to breed eggs, so considering that there are still many farmers in China who need roosters. So the rooster still has the meaning of existence. At the same time, in some rural cultures, chickens are used to worship the sky, and chickens that worship the sky must be roosters.
Second, people still need roosters to produce sperm. Yes, now it means ... hens are artificially inseminated. But there are still many factories that need to breed cocks, because after all, cocks will give birth to these sperm, so hens can be artificially bred and inseminated. So the significance of rooster's existence now is to breed a new generation of chickens with sperm for subsequent hens.
Third, the rooster is big and edible. In fact, the last feature is that the rooster is large in size and beautiful in color, which can be used to make chicken blankets and various wool products. And some places will eat roosters, because they are big and have delicate meat. Compared with other species, their nutritional value is not bad, so they are especially suitable for sick people.
