Why did the pigeon peck each other

The reason why pigeons peck each other because they are pairing.At this time, there is no need to worry about the henters, but we still need to pay attention to it appropriately to prevent the male pigeons from being excited to peck and hurt the hen.In addition, when they are about to produce eggs, the male pigeons will always chase the hen pigeons to peck, prompting them to return to the nest to produce eggs.At this time, the breeder should prepare them for breeding nest boxes in advance.
