Strangest Egg Color I’ve Ever Gotten June 26, 2015

If you’ve kept chickens for any period of time, you’ve probably seen some unusual eggs. When hens first start laying their eggs may be quite small or even quite large double yolkers! They may be shell-less. Egg color can be stunning, too. In addition to white and brown, egg color may be green, chocolate, blue, olive, pink, cream, and colors in between, depending on what varieties you keep (and this is certainly strange to people used to white grocery store eggs!). Hens from time to time will lay tiny, yolkless “fairy eggs.” Then there are the eggs that have a funny shape or texture.

Unusual eggs are not usually a cause for concern, particularly if it’s just a temporary situation. Being stressed out can cause your hens to lay eggs that are smaller or larger, or to have ripples or waves in the shell. Textural differences in parts of the shell can cause color to be heavier or lighter in places, usually in mottled speckles, spots or stripes. And some differences aren’t caused by stress at all. Some breeds’ eggs naturally have a satiny sheen, while other breeds produce eggs with a dull, matte finish. Really, the variety is wonderful!

But one of my hens—and I’m not sure who, since this is not her usual egg color–has given me the strangest I’ve ever seen before… at least in person.

Her egg has swirls.

egg color: blue, green, chocolate, brown, cream

The swirly egg is in the center, surrounded by blue, green, chocolate, medium brown , and cream eggs. And the swirl is such a dark blue!

Now, contrary to popular belief, the color of the shell doesn’t indicate an egg’s healthfulness. My grandma used to tell me that brown shelled eggs were healthier… and she was right, in a way. At the time, commercial eggs were almost always white, while eggs produced by a real farm where the layers had outdoor access were more likely to be brown. And hens raised with access to pasture lay much, MUCH more nutritious eggs. But now white/brown egg color is hardly an indicator, since conventionally produced eggs are often brown, too.

But I do have to wonder what she’d have made of my swirly blue egg.

Now we can theorize as to why egg color differs for different birds. We know what substances create blue eggs, green eggs, brown eggs and so forth. Some breeds, like the Welsummer, even regularly lay speckled eggs. But no one lays swirls.

No one but a hen in my flock, who gave me this swirly egg color after a particularly strong storm. By the color of the swirl, it must be one of my Easter Eggers or Favaucanas… now I just have to figure out which one. And I have to figure out how I can convince her to do it again! Do you think a bribe will work?

That is a pretty cool looking egg. My 21 week old leghorn just started laying five days ago and her eggs are smaller than what she is supposed to lay. Her breed is supposed to lay extra-large eggs. They are medium right now but when are they supposed to get bigger?

They usually lay slightly smaller eggs for a month or two before they reach their full size for the breed. Sometimes hens that are a few years old lay even larger eggs (although they tend to lay fewer). Congrats on your new eggs! 🙂

Who laid that GORGEOUS “Green Egg”? It doesn’t look live an Olive Egger. EE, Isbars, Favucana? I must know WHO (and then buy that breed)!

This answer will be something of a disappointment I’m afraid: it was laid by an Easter Egger. Easter eggers are more or less mutts that carry the blue/green egg color gene. Some EEs lay blue, some green, all in different shades. So buying an EE will not get you that particular shade of green, necessarily. But a flock of EEs make for such a beautiful egg basket! The first chickens I ever “met” in person were a flock of bantam EEs, and I went home with two dozen teeny blue and green eggs that were so pretty it was hard to make myself crack them. I was in love… and the rest is history! 😉
