Did you ever wonder what makes so many beautiful egg colors?
Did you know ALL eggs start out white in color! It is pigments deposited in the hen’s oviduct that creates all the beautiful colors!
Blue egg layers, like Ameraucana and Cream Legbars, have the pigment oocyanin deposited on the egg, permeating the shell resulting in the interior and exterior of the egg shell being the same blue color.
Chickens that lay brown tinted eggs deposit the pigment protoporphyrin on the eggs late in the process and just before the egg is laid. The pigment does not penetrate the interior of the egg, but tints only the surface of the egg. This is why on super dark layers, like Marans, you can often see scratches in the pigment.
