The most obvious difference is the color of the eggshell. White eggs have a white shell while brown eggs have a brown one. This difference is due to the breed of the chicken that lays the egg.
Chicken Breed
White eggs are typically laid by chickens with white feathers and earlobes, such as leghorns. Brown eggs are laid by chickens with red or brown feathers and earlobes, like Rhode Island Reds or Plymouth Rocks.
Egg Size
There is a common misconception that brown eggs are larger than white eggs, but egg size is determined by the age and breed of the chicken, not the color of the eggshell.
Cost
Rather than the eggshell color, the apparent cost difference between brown and white eggs is frequently linked to elements like chicken food, housing, and production practices.
Nutritional Content
Despite popular belief, there is no nutritional difference between white and brown eggs. Both types contain similar amounts of protein, fat, vitamins, and minerals.
Market Preference
In some regions, there may be a preference for one color of egg over the other but this is largely a matter of cultural or regional preference rather than any inherent difference in quality or taste.
