Because the cock has a clock in his brain that can tell the time. So the rooster is really smart. The cleverness of roosters is discovered through research. Roosters can be alert to danger and fight back. Roosters can communicate more complicated information. Cocks sometimes crow for selfish reasons. Chickens will pay attention to the degree of danger of themselves and their competitors, and are more willing to call the police when their own risk is the smallest and the risk of competitors is higher. If you are lucky, you can not only protect your hen, but also get rid of another rooster.
Cock's communication ability
The communication ability of roosters can even be compared with that of primates who use complex signals to convey their personal wishes. When making a choice, people who are chickens will use their own experience and relevant information to make judgments and be able to deal with relatively complicated problems. You can even put yourself in the same perspective to see the danger. These studies show that some complex cognitive behaviors exist widely in the animal kingdom.
