You’ve probably noticed at the grocery store or breakfast table that the shells of some eggs are brown, while others are white. Why are there two different colors of eggs? Is there any other difference between them, aside from color?
The answer is simple: aside from their color, brown and white eggs are exactly the same in every way, including taste and nutrition. The only reason there are two different colors of eggs is because some hens (usually dark-feathered ones) lay brown eggs, while others (usually white-feathered ones) lay white eggs!
People sometimes think that brown eggs must be better than white ones because the brown eggs usually cost more. The only reason brown eggs are more expensive is that the hens who lay brown eggs tend to eat more food, and are more expensive for the farmer to raise!

Have you ever seen a chicken’s earlobe? The skin on the side of a chicken’s face is usually referred to as the “earlobe.”
If you’re ever wondering what color eggs a hen will produce, you can often figure it out just by looking at the “earlobe”! Although it’s not true for all types, a hen’s earlobe color can often indicate the color of eggs it lays! – The darker the earlobe, the darker the eggshell color! NEAT!
