What kind of pigeon is it?

The one in your photo is called raindrop. Domestic pigeons are generally carrier pigeons and ornamental pigeons. If you just want to raise ornamental pigeons, they are beautiful and not easy to fly away. If you have other plans, such as taking part in the competition, then raise some good varieties of homing pigeons. Of course, that would be expensive. Pigeons are generally gray, purple, raindrops, white stripes, unicorn flowers and the like. Pigeons of excellent pedigree are all from Belgium and Taiwan Province Province, such as Zhan Sen and Computer Pigeons.
