How do roosters reproduce?

Roosters have reproductive organs not unlike mammals, with testes that produce sperm. The sperm travel down tubes called vas deferens to sperm sacs. During mating — an unceremonious affair that lasts less than 20 seconds — the sperm leave the male through an opening called a cloaca , and enter the female through an entrance to her reproductive tract, called the oviduct. From there, the sperm make their journey through the reproductive organs of the female. In a trip that may take a week or more, they swim through the hen’s shell gland, then a narrowing in her reproductive tract called the isthmus, followed by the magnum and the infundibulum. There, they await the arrival of eggs in the process of forming.

Can an egg yield a chick?

An egg will only yield a chick if the hen has mated with a rooster before the egg was formed . Most production-oriented farms don’t have a rooster milling about, unless it’s time to make a new batch of egg-laying hens. This means that almost all eggs in the supermarket are unfertilized.

Where do hens get their eggs?

The Hen Also Does Hers. A hen’s eggs begin as yolks in the ovary, and once released they pass into the infundibulum, a funnel-shaped organ where the sperm are waiting. There they are fertilized, and pass out of the chicken via the same route the sperm entered. The egg white gathers around the yolk in the magnum.

When do chickens breed?

You can tell whether the farm egg you just cracked open for your breakfast is fertilized or not. Examine the egg for the germinal disc, a white spot floating above the surface of the yolk. The germinal disk of a sterile egg contains only the hen’s cells and is fully white in color. In a fertilized egg, the germinal disk contains the merged female and male cells. These will divide and multiply, leading to the development of a chick embryo. A fertilized germinal disk looks like a tiny white donut or bullseye—a white ring with a clear center.
