How eggshells get their color?

Every single egg start out as a shade of white; those that get laid in other colors apart from white get their color from pigments they attract while they were passing through a hen's oviduct. An egg takes 26 hours to pass through a hen's ovuduct. The shell however takes about 20 hours to fully develop.

Hens that lay brown colored eggs transfer the pigment known as protoporphyrin on the eggs late in the process of developing the eggshell. For that reason, the pigment does not pass through the interior of the egg and only the surface of the egg. This is why brown eggs are white on the inside. The chickens known as Ameraucana gets the pigment known as oocyanin treansferred onto the egg while it passes through the oviduct. The oocyanin pignent passes through the shell and colors the interior a shade of blue just like the exterior.

Why chickens lay different color eggs
The simple answer is genetics. There are a lot of different colors of eggs in the world, such as a robin's-egg-blue and darkly speckled quail eggs. In chickens, there are two basic colors of egg shell: blue and white. In addition to the basic shell color, there a many genes for brown coatings that are put on the egg by the bird as the egg is being laid. Blue is dominant over white, so a chicken with one gene for blue shells and one for white shells will lay blue eggs. Adding different brown coatings over these blue or white shells means that different breeds of chickens can lay many colors of eggs. This is highly simplified, but this is basically how chicken egg color genetics works: Blue shell genes, no coating genes: blue eggs White shell genes, no coating genes: white eggs One blue shell gene, one white shell gene, no coating genes: blue eggs Blue shell color + brown coating gene(s) = green eggs White shell color + brown coating gene(s) = brown eggs Since breeds of any kind are basically human genetic engineering over time, humans have fixed egg color and coating genes in different breeds of chickens. Ameraucanas and Araucanas must lay a blue egg, or they are not those breeds. Marans must lay an egg with at least a certain darkness of brown shell, or they are not Marans. Leghorns must lay a white egg. Etc. Etc. Cross-bred chickens such as the Easter Egger will have lots of variability of egg color between individuals, laying brown, green, blue, cream, or even a pinkish egg. It's all genetics.
