Brown eggs are eggs that come from certain breeds of chickens, such as the Rhode Island Red and Plymouth Rock. The color of the eggshell is determined by the genetics of the hen, with brown eggs typically being laid by hens with red feathers. Nutritionally, brown eggs are similar to white eggs, containing comparable amounts of protein, vitamins, and minerals. The perception that brown eggs are healthier or more organic than white eggs is a common myth; the nutritional value is primarily influenced by the hen's diet rather than the color of the eggshell.
