How do chickens lay eggs?
Chickens — like other birds — lay fertilized eggs via sexual reproduction. A rooster mates with a hen, who then lays a fertilized egg.
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?
In outdoor conditions, chickens will breed when the days begin to get long in spring. While the rooster will mate with his hens throughout the year, she typically only incubates eggs when conditions are optimal. A hen choosing to incubate eggs is said to have "gone broody.". The Rooster Does His Part.

How Many Eggs Fertilize at Once?
At first, the rooster fertilizes one egg, that’s referred to as the egg of the day. However, sperm are placed into sperm pockets and fertilized in the eggs in the next few days. This sperm remains viable for up to 2 weeks, but five days is the standard time frame.
What happens if there is no reaction to an egg?
If there is no reaction, then it’s unlikely that there was ever a fertilization event or even sperm in contact with the yolk membrane of this egg at all.

Meanwhile, it’s fertilized and passes the chicken through the same route where sperm entered. The white part of the egg gathers the yolk around in the magnum.
What are the resources that eggs need to grow?

What is the purpose of a cloaca?
A cloaca is a part of a bird. It is the one entrance and exit hole through from which they urinate, defecate and transfer sperm. Unlike most mammals, a female chicken has only one rear hole that performs three important functions. It is the exit point for feces and eggs and the entry point for sperm to enter.

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.
