Curly feathers Rooster belongs to the peasant Zhang Yan of the mountain village Sitszetsun. The owner says that the rooster hatched in April of this year. First, it does not differ from the other chickens and he eats the same food, that’s all. But once started forming feathers, they gradually became curly. Zhang Yang found that this miracle was very stubborn and cocky. He does not admit to the trough of other hens and cocks, until he feels full. Employee of the county Department of Livestock said that he is working in this industry for many years, but never heard roosters with curly feathers. He suggested that this phenomenon is associated with environmental, genetic and other factors that caused a genetic mutation in the cock and its unusual feathers.
