The same is true of crowing: the rooster with the highest status in a group is always the first to crow to announce the arrival of the morning, and the other roosters will crow in turn according to their social status.
Extended data
The researchers found that in a group of four cocks, the one with the highest social status crows first every morning, and then its subordinates crow in descending order of social status. A rooster in a lower position crows less than a rooster in a higher position.
When the rooster with the highest position is removed from the experiment, the rooster with the second highest position will crow first, which shows that the existence of the dominant rooster inhibits the crowing of the subordinate rooster before dawn.
People's Daily Online-A study in Japan found that cock crowing is not random, it depends on the generation.
