Fun Food Fact! You may have noticed that not all eggs you can buy or collect from your chickens look the same. Some have a white shell, others a brown shell. Then, when you crack them open, some yolks are very yellow, while others appear to be extremely orange. Did you ever wonder what causes these differences in appearance?
Fun Food Fact about Eggs and their colour differences
Egg Shells
The colour of an eggshell has no influence on the taste of the egg itself but is determined by the race of the chickens. Some chickens produce white eggs, while others produce brown eggs. [1]McGee, Harold. On Food And Cooking. New York: Scribner, 2011. Print.
Egg Yolks
The colour of the yolk, however, depends on the feed that the chicken consumes. That colour is not an indicator of how fresh the egg is or the number of vitamins in it. In some cases, feed suppliers can influence the colour of the yolk by adding more additives to the chicken feed.[2]Nys, Y., Bain, M., & Immerseel, F. V. (2011).

(To make things even more exciting, our pee can also change colour, depending on the food we eat ;).)
