The color of an egg is dependent on what breed of hen a farm has. White eggs are usually laid by the leghorn hen breed, and brown eggs are laid by a breed related to the Rhode Island Red, but many different breeds can lay eggs. One way to tell what color egg a hen will lay is by checking out their earlobes. Yes, hens have earlobes. Chickens with white earlobes will lay white eggs, while pink or gray earlobe ones will lay brown, cream, or even blue eggs.
The biggest factor in the perceived difference between brown and white eggs is the chicken’s diet. What a chicken is fed determines the quality of the egg and what the color of the yolk will look like. Another factor is how fresh the egg is since it has been laid. No one wants to eat an egg that’s been sitting around. That doesn’t make for tasty eating. So if you want a good egg, just buy one from a chicken that’s had a happy life.
