Cocks, like people and all kinds of creatures, have biological clocks. Every living thing has its own biological clock, which roughly determines when we should study, work, eat or sleep. Because the earth has day and night, most people work and study during the day and rest at night. So is the rooster. In ancient times, people didn't have clocks, so they did? Smell the chicken dancing? Because roosters crow regularly at four o'clock every morning, why? The main reason why the rooster crows regularly at four o'clock every morning is that the rooster's own biological clock makes it crow. That is to say, it is innate, and every rooster will crow naturally at that time. Also, the rooster's crowing will also be disturbed by external factors, such as the change of outdoor light and sound, which will affect the rooster's crowing time, but these factors are also controlled by the rooster's own biological clock. According to the research of zoologists, roosters are very sensitive to the changes of outdoor light and sound, so whenever outdoor sunlight starts to shine, roosters will get up and start crowing, and these lights are very weak, so people usually think it is still night.
Moreover, the cock crowing is also related to the cock's own androgen. Like humans, cocks have more male hormones and hens have more female hormones. Androgen also determines that roosters will crow under certain circumstances. It has been found that if the androgen in hens increases, hens will also start to crow. Also, the rooster crowing is actually a manifestation of declaring territory. Generally speaking, the first rooster that crows every day in a group of henhouses is the most powerful rooster in the henhouse.
After years of evolution, rooster crowing has become a fixed and unaffected animal behavior. Even if the light, sound and other conditions are changed, roosters will crow, because this crowing behavior has been carved into their genes and become roosters? Patents? Yes
