The pigment therefore does not penetrate the interior of the egg, but tints only the surface of the egg, which is why brown eggs are white on the interior. In the case of an Olive Egger, a brown pigment overlays a blue egg shell resulting in a green egg. The darker the brown pigment the more olive color of the resulting egg.
Consider sharing your chicken raising experience with youth. This article was published by Michigan State University Extension. Why are chicken eggs different colors?
Did you find this article useful? The pear-shaped eggs of a common murre Uria aalge can sport a blue hue, be speckled or feature brown streaks. And while we're on the subject of color and genetics: Curious as to the origins of the iconic yellow legs of the Leghorn chicken?
While scientists dating back to Charles Darwin have identified the domestic chicken Gallus gallus domesticus as a domesticated subspecies of the red junglefowl Gallus gallus , Swedish researchers in a study identified early crossbreeding with the grey junglefowl Gallus sonneratii as introducing the genes behind the modern chicken's yellow legs. Oh, but that egg-inside-an-egg story that's going around the internet right now?
That's another thing entirely, and involves an egg accidentally reversing its course in the oviduct. Should chicken eggs be kept refrigerated or at room temperature? It depends on whether you live in a country Australia, Japan and the United States, for instance that requires eggs produced for commercial sale be washed. This process protects against salmonella, but also removes a waxy shell coating that naturally defends eggs against microorganisms, thereby necessitating refrigeration.

Animal Facts. A local farmers market in Annandale, Virginia, sells natural chicken eggs. Different chickens lay eggs of different colors solely because of their genetic makeup. PAUL J. Now That's Interesting. Some chickens lay colored eggs because of the breed. Nestled in-between blue egg layers and green egg layers is a good place to mention Easter Eggers.
The genetics involved in determining exactly which color an Easter Egger will lay is a little complex. It suffices to say these chickens possess the gene that allows them to produce blue-colored eggs. Depending upon the egg pigment variation of the breed they crossed with their mom, the resulting egg color your hen produces will result from this. Easter Eggers vary widely in color and conformation and are typically exceptionally friendly and hardy.
Since they are usually quite friendly to children and humans in general, they are an excellent choice for a family flock. Although what follows in this category may seem to be a Dr. Seuss favorite, the green eggs we refer to are more of an olive color. Who lays these interesting olive-colored eggs? The appropriately named Olive Eggers, of course!
To get an Olive Egger, you need to mix a green egg laying Easter Egger with a dark brown egg laying chicken, like a Marans or a Welsummer. These hens are good layers of about colorful and large-sized eggs per year. Because of the genetic diversity in Olive Eggers, there tend to be a lot of individualized personalities.
But in general, Olive Eggers are generally very docile and friendly chickens that tend to do well with other chickens. If Welsummers are in the mix, your Olive Eggers will likely be especially intelligent chickens. This is somewhat typical of hybrid animals of any species.
Ultimately, though, it comes down to individual variation within breeds. There is no one breed you can pick to ensure a pink egg layer, but olive eggers, blue egg layers, or dark brown egg-laying species bred with a creamy colored egg layer may produce a chicken that lays something along the lines of pink. A chicken that lays chocolate eggs is not what it sounds like. If you think about it, eggs that are a rich dark brown color on the outside will probably be prevalent with folks that prefer brown eggs vs.
Three breeds that tend to lay dark brown chocolate colored eggs are Welsummer , Marans , and Pendescena. The Welsummer was developed in the early 20th century. It originates from a small village in the eastern Netherlands called Welsum.
Not only does the Welsummer lay beautiful dark brown colored eggs, but these beauties are wonderfully large and may number up to per year. Like its eggs, the Welsummer is a large-sized bird — which means it needs more space and loves to roam around.
