One, eating and tweets. All high-yielding hens are constantly feeding on feed and giggling rhythmically in the morning during egg production, which is very cheerful and sweet. After the egg lays, it shouts loudly.
Second, the size and color of chicken cocks and meat clams. The high-yield cocks and meat scramble are more developed, the crowns are more than one side, and the color is bright and red, and it feels warm when touched. Low-yielding combs and meat atrophy, dry, pale and dull.
Third, the feather condition. Most of the high-yielding chickens use eggs for egg production, so the feathers are incomplete and the color is dark. Lower-produced chicken feathers are better. High-yielding broiler chickens tend to have fewer feathers and exposed skin because of cock mating and back and neck.
Fourth, the number of mating. Under natural mating conditions, high-yield hens are often associated with cockerels. When they see a cock, they often take the initiative to squat and accept mating. Low-yield or discontinued hens evade and stay away from the cock.
Fifth, the cloacal morphology. The high-yielding hens who often lay eggs have a cloacally rounded, enlarged, loose, semi-open state. The hand is pressed at the root of the appendix, and the vagina is turned outwards. Artificial insemination is particularly easy for the anus. Low-yield hens have a cloaca that is small, tight, and dry, and it is difficult to manually turn the anus.
Sixth, the size of pubic bone spacing. High-yielding hens have large pubic bone spacing and can accommodate more than three fingers. The pubis of low-yielding hens lacks elasticity and hardness, and the distance between the two pubic bones is small, only containing 1-2 fingers.
Seven, the size of the abdomen. High-yield chickens have well-developed digestive organs and genital organs. Therefore, the abdomen is deep and soft, and the distance between the pubis and the sternum is wide and can accommodate more than one palm. However, chickens with large and hard belly are often low-yielding chickens. Generally, low-yielding chickens are small and tight in the abdomen, and the pubic and sternal ends are narrow and can only contain 2-3 fingers.
Eight, the depth of skin pigments. High-yielding hens' pigments are transferred into the eggs and the skin fades and white, while the low-yielding hens have yellower skin. The order in which the skin color fades is: anus, eye socket, ear lobe, ankle, ankle.
Nine, moulting situation. Whereas the high-yielding hens have late moults and have a quick moult, some high-yielding hens have feather-producing eggs. Lower-yielding hens were earlier than the moults and had a longer moult.
Ten, behavioral dynamics. High-yielding hens lively and active, diligent in feeding, docile temperament, not afraid of people, returning home early and late return. Low-producing hens are slow to move, do not like to eat, often hide on the side, have nesting, timid and afraid of people.
