What is a fertillised hen egg?

Here's what makes it different from a regular egg:

* It has the potential to develop into a chick. The fertilized egg contains a developing embryo, which can grow into a chick if incubated under the right conditions.

* It has a larger germinal disc. This is the small, whitish spot on the yolk where the embryo starts to develop. In fertilized eggs, the germinal disc is larger and more prominent.

* It's less common. Most hens lay unfertilized eggs, as they don't have regular contact with roosters. Fertilized eggs are usually found on farms where roosters are present.

However, it's important to note that:

* Fertilized eggs are not always noticeable. You can't always tell by looking at an egg if it's been fertilized.

* Fertilized eggs are still safe to eat. There is no difference in taste or safety between fertilized and unfertilized eggs. The embryo doesn't develop into a chick unless the egg is incubated.

So, in short, a fertilized hen egg is an egg that has the potential to become a chick but is perfectly safe to eat!
