The main difference between brown and white eggs lies in the breed of the chicken that laid them. Brown eggs are laid by red-feathered chickens, while white eggs are laid by white-feathered chickens. Generally, brown eggs are more expensive than white eggs due to the higher cost of keeping red-feathered chickens. Brown eggs also tend to be larger than white eggs and have thicker shells. The taste and nutritional content of the eggs is generally the same, regardless of the color of the shell.
The color of the eggshell is determined by the breed of the chicken, not by the feed or the diet of the chicken. Brown eggs are laid by red-feathered chickens, while white eggs are laid by white-feathered chickens. Red-feathered chickens are larger than white-feathered chickens, so they usually require more food, which makes them more expensive to keep. This is why brown eggs are usually more expensive than white eggs.
In terms of nutrition, the two types of eggs are essentially the same. The nutritional content of eggs is determined by the diet of the chicken, not by the color of the shell. Both brown and white eggs contain high-quality proteins, vitamins, minerals, and essential fatty acids. They are also a good source of choline, which is important for brain health.
