How are Eggs Formed in Chickens?
To understand the process of egg formation in poultry, let’s take a closer look at the step-by-step journey that an egg undergoes within a chicken’s body:
1. Ovarian Development:
The process begins with the development of the ovary, where small ova (egg cells) are produced and matured.
The ovary contains thousands of tiny follicles, each housing an immature ovum.
2. Ovulation:
During ovulation, a mature ovum is released from the ovary and travels into the oviduct, a long tube-like structure responsible for the formation of the egg.
3. Fertilization:
If the hen has mated with a rooster, the released ovum may be fertilized by sperm within the oviduct.
Fertilization typically occurs in the upper region of the oviduct.

4. Albumen Formation:
As the fertilized ovum moves further down the oviduct, it enters the magnum section, where the albumen, or egg white, is secreted around the ovum.
The albumen provides a protective cushion and a source of nourishment for the developing embryo.
5. Shell Formation:
In the next section of the oviduct, called the isthmus, the egg receives its protective shell.
The shell is formed from a combination of calcium carbonate and other minerals, which are gradually deposited around the egg.
6. Pigmentation and Cuticle Formation:
Before the egg is laid, it passes through the shell gland or uterus.
Here, pigments are added to the shell, giving it its characteristic color.
Additionally, a protective cuticle is formed on the shell’s surface, helping to prevent microbial contamination.
7. Laying the Egg:
Finally, the fully formed egg is laid through the cloaca, the common opening for excretion and reproduction in birds.
The egg is then ready to get served on our breakfast tables!
Conclusion
The process of egg formation in poultry is an amazing journey of nature.
From the initial development of the ovum to the formation of the protective shell, each step contributes to the creation of a nutritious and versatile food source.
Next time you crack open an egg, take a moment to appreciate the incredible journey it underwent within the chicken’s body.
