Egg Science Facts

Time for some egg facts! Ever wonder what makes your egg shell so brittle, or why you get an especially bright yolk sometimes? Egg shells are made from calcium carbonate, a substance that occurs naturally in many forms–for instance, limestone and chalk are both members of the same family! Beta carotene, a pigment found in many plants and fruits–like carrots!–is sometimes added to feed to provide that extra bit of yellow in the yolk.
