The Difference Between White and Brown Eggs
Have you ever wondered what the difference is between brown and white-shelled eggs? Brown eggs often cost more at the market or grocery store. The difference is not in the quality, but in the size of the egg. Generally, white-feathered hens with white earlobes lay white eggs, while hens with red earlobes, often brown hens, lay brown eggs. Brown eggs are typically bigger than white eggs, which is why they cost more. You can’t compare the nutritional value of brown and white eggs like you can brown and white bread products. To compare eggs, you need to look at what the hens are fed, rather than the colour of the shell.
