Breeding pigeons have been raised for about 6 months, and various functions of sexual organs and bodies have been improved, so they can breed in pairs. There is affection between male and female pigeons, and they lay eggs in about 10 days.

Pigeons usually have two ways of pairing: natural pairing and artificial pairing.

Natural pairing is to let flocks of pigeons find their partners and pair them in pairs. Its advantage is convenience and no labor. But there are many shortcomings: First, it is easy to cause inbreeding. Because pigeons lay two eggs at a time, mostly one male and one female. When they grow up, brothers and sisters may pair up, leading to inbreeding; Second, premature mating is easy to occur, especially in small pigeon farms, where the number of young pigeons is small, pigeons who leave their parents are often locked together, and the pigeon age is uneven. In this way, some pigeons that cooperate with themselves are mature, and some are premature before they are fully mature; Third, naturally paired pigeons often lead to differences in breed, coat color, body shape and weight, which is not conducive to obtaining excellent offspring. Manual pairing can overcome the problems existing in natural pairing.

Artificial pairing is a way to artificially pair pigeons. This method is suitable for the selection of various pigeon farms, domestic pigeon houses and varieties, especially for cage pigeons.
