Why does the chicken crow?

Crooster crow is a common phenomenon. Every day before dawn, the farmer's roosters crow loudly, as if they have encountered some great happy event. But you don't know what kind of torture these cocks endured in the darkness before dawn. This is definitely not sensational. To explain why roosters crow, we must first talk about their poor eyesight.

Chicken is a type of bird. Most birds are active during the day, and their vision during the day is of course pretty good, but at night, except for some birds that are active at night, such as owls, most other birds have poor vision, and some are almost blind. No exception. So if someone goes to catch chickens in the dark, they rarely resist. Even if someone shines a flashlight on them, they don't know how to hide.

In addition, the rooster is also a very aggressive animal. It crows to warn other roosters not to come to its territory, otherwise they will not be welcome. The rooster also crows to attract the attention of the hen, reminding the hen that there is a beautiful man here and must not go anywhere else.
