From the mature period, wearing "glasses" on the cock's nose until the time of slaughter can effectively avoid cock fighting.
Cockfighting has something to do with looking directly at each other. The so-called "glasses" are a piece of red shielding film, which can focus the cock's eyes from the front to the sides, thus reducing fighting.
About 50 of the first chickens died in fighting. After wearing glasses, the second batch of slaughtered chickens did not die in the fight.
The history of chickens with glasses:
The history of chicken glasses should start from Britain. According to the records of the British National Patent Office, chickens wear glasses not because of myopia, but to protect their eyes from being pecked blind. It is reported that in a chicken farm in England, one day, the farmer found that some of his chickens stopped eating, were thin and hungry, walked around and kept hitting the wall.
The farmer was very surprised. After careful observation, he found that the chicken was blind. It turned out that when the chickens were eating, because they were rushing to eat, the powerful chickens pecked at each other's eyes and pecked blind. In order to prevent more chickens from being pecked blind, the farmer tried every means and finally invented chicken glasses to protect the eyes of chickens.
