The natural color of eggs can vary depending on the species of the bird laying them. In the case of chicken eggs, the natural color is typically light brown or white. The breed of the chicken influences the eggshell color, with some breeds producing eggs that are cream or tinted shades as well. Duck eggs, on the other hand, usually have a thicker shell and appear off-white to light blue or green. Certain breeds of ducks may lay eggs with unique colors, such as blue Muscovy duck eggs. Other birds, like quails and pheasants, lay eggs that can be speckled or have different colors, such as light brown or olive. It's essential to note that eggshell color doesn't affect the nutritional value or taste of the egg. The color of the eggshell is primarily determined by the genetics of the bird and doesn't indicate any specific difference in the egg's quality.
