Why are some eggs brown and white?

The color of an egg shell is determined by the breed of chicken that laid it. Here's the breakdown:

* White eggs: Chickens with white earlobes lay white eggs. These breeds often have white feathers as well.

* Brown eggs: Chickens with red earlobes lay brown eggs. This is due to a pigment called protoporphyrin, which is deposited in the eggshell as it forms.

It's important to note:

* Egg color doesn't affect taste or nutritional value. Both brown and white eggs are equally nutritious.

* Some breeds lay blue or green eggs. These are rarer and are produced by breeds like Ameraucana and Araucana chickens.

So, the next time you're choosing eggs at the grocery store, remember that color is just a matter of breed, not quality!
