When the hen chooses a mate, she will watch the battle, and the rooster that wins will be favored by them. BecauseThe hen needs this rooster to provide territory, so that there is food to feed the chicks, and at the same time, this strong rooster can provide protection to the chicks.

So the purpose of the rooster's crowing is toSwear your status, tooWarn competitorswithPredatorsStay away. Flocks of chickens haveStrict hierarchy, The status of a single rooster is never as high as the position of the king of chickens, so this kind of thing can only be the first, and other roosters can't crow at will.

If something happens to the leader of the flock, the rooster, then the life of the orphans and widows will become extremely difficult, and without the rooster to provide protection, a flock is in danger of being wiped out. On the occasion of life and deathThe hen decided to save her flock

But the habits of chickens make themThere must be a leader, so in chicken farms, where there are no roosters, there isThe hen begins to develop in the direction of the rooster, chirp and mate without falling. Such hens do not produce eggs anymore and have no value for chicken farms, so they are treated as broilers.
