Can a hen lay eggs at 16 weeks old?

It's highly unlikely for a hen to lay eggs at 16 weeks old.

Here's why:

* Average Laying Age: Most chickens start laying eggs around 18-24 weeks of age, depending on the breed.

* Maturity: Hens need to reach sexual maturity before they can lay eggs, and this process typically takes around 18-24 weeks.

* Factors Affecting Laying Age: Factors such as breed, nutrition, and environmental conditions can influence the age at which a hen starts laying. Some breeds may start earlier than others.

While it's rare, there might be exceptional cases where a hen lays an egg earlier than expected. However, it's not the norm.
