Grasping the identification method of pigeon age is of great significance for timely breeding and selection of improved varieties. The age of the pigeons can usually be identified from the following "seven observations": A look at the mouth of the mouth: young pigeons mouth a sharp, narrow and thin mouth on both sides, no scab, more than a year's pigeons slightly scab. Adult pigeons are thick and short, their ends are hard and slippery, their mouths are thick and rough, and they have large scabs. Second, look at nasal aneurysm: The neostigma of the pigeon is ruddy, and the nasal tumor of the young pigeon is light red and shiny. The nose tumor of more than two years has a thin pink color. The nasal tumor is large and soft, moist and shiny. Pigeons more than four or five years old are pink and rough. Look at the toes three times: The young pigeons are soft-feeling, the scales are soft and flat, the scales are not obvious, the colors are red, the toenails are soft and pointed, and the texture is soft. The adult doves are stout, with coarse scales, clear scales, dark reds, and stiff nails. Look at the floor mats: The mats of young pigeons are thin and soft; the mats of adult pigeons are thick and hard, rough and dark in color. 5 Look at the feathers: The main wing of the pigeon can be used to identify the month age of the youngster. There are 10 main wing feathers of the pigeons. At the age of 2 months, the first root will be changed. Then one root will be replaced every 13 days to 16 days. When the last one is changed, the pigeons will be about 6 months old and mature. At the time, paired production can begin. There are a total of 12 pigeons' main wing feathers, which can be used to identify the age of the old birds. Auxiliary wing feathers are replaced one by one from the inside to the outside each year. Replaced feathers appear slightly darker and neat. Watching the spectacles: The more wrinkles on the scalp skin of pigeons, the older they are. Seven see cavity capsule: the size of the capsule from the pigeon cavity, with or without identification of pigeon age. The bursa on the cavities of the pigeons is located above the cloaca, the bursa of the young birds is relatively large, and they become smaller when they are old birds. After a few years, the bursa on the cavity becomes very small, or there is only a trace left.
