How to recognize the age of the rooster

1, look at the beak: the tip of the shorter age of the chicken is thinner, the two sides of the beak is getting narrower and narrower, and will not form hard bumps, more than a year of the chicken will form hard bumps.

2, look at the foot pads: immature chicken feet and thin and soft, adult chicken pads thick and hard, rough and dark.

3. Look at the foot abductions: the older the chicken, the longer, harder and rougher the foot abductions.

< p>Mating occurs when the rooster rides on the hen's back and uses anus to anus for insemination. Although eggs laid by fertilized hens can hatch chicks, it doesn't mean that the eggs are the culmination of the two, and unfertilized hens can also lay eggs. The reproductive system of chickens differs from that of fetal mammals. The testes and epididymis of the rooster are in the abdominal cavity, the copulatory organs are degenerated genital protuberances, and the sperm head is long and conical. Sperm can survive for up to 24 days in the spermatogonial fossa in the hen's oviduct and are capable of fertilization.

Hens can ovulate every 25 hours or so, only the left ovary and oviduct develop, and the fertilized egg will pause in development before reaching the critical level of hatching (24°C) after it is discharged from the hen's body.

The reproductive system of the rooster consists of the testes, epididymis, vas deferens and coitus. The most important thing for artificial inseminators to understand is the construction of the coitus in the rooster. The rooster does not have a penis like mammals, but has a four-part coitus consisting of a teat, a glandular body, a penis and a lymphatic fold. The coitus is located ventral to the cloaca and is normally completely hidden within the cloaca.

When sexually aroused, the lymphatic vessels in the glandular body, penis and lymphatic folds are connected to each other, the lymphatic folds are erected, and the lymphatic fluid flows into the penis so that it expands and forms a deepened longitudinal groove at the midline, and the body of the penis at the front of the midline (the central white body) protrudes in front because of the inflow of lymphatic fluid, and the whole penis is pushed out of the ventral side of the anus and inserted into the anus of the hens at this time.
