Though brown eggs are often more expensive, the shade of an eggshell says nothing about the quality of what's inside it. According to The Kitchn, the only difference between brown eggs and white eggs lies in the breed of the chicken that laid them. You may have heard the myth that white-feathered chickens always lay white eggs and brown chickens lay brown eggs. White leghorns—which lay white eggs—produce more eggs on cheaper diets, so they are favored by factory farms. Breeds that lay brown eggs, like Rhode Island reds, require higher quality food and more of it, which promotes higher quality eggs.
