What are the dots on a candled chicken egg?

Here's how it works:

* Air Chamber Formation: When a chicken egg is laid, it contains a small air pocket at the blunt end. This is the beginning of the air cell.

* Candling: When you shine a light through the egg (candling), the air cell appears as a dark spot.

* Air Cell Growth: As the egg ages, the contents within the shell contract, and the air cell gradually increases in size.

* Candling Indicators: The size and shape of the air cell can indicate the age and freshness of the egg. A small, round air cell suggests a fresh egg, while a large, elongated air cell indicates an older egg.

So, the dots you see are not blemishes or defects, but rather a natural part of the egg's structure.
