Egg Color Chart by Breed: Which Hens Lay What Color
An egg color chart by breed showing which chickens lay white, brown, dark chocolate, blue, green, and cream eggs, plus what determines egg shell color and shade.
Quick answer: Egg shell color is set by breed genetics, not diet. White eggs come from Leghorns and Polish; brown eggs from Rhode Island Reds, Australorps, Plymouth Rocks, and most common breeds; dark chocolate-brown eggs from Marans and Welsummers; blue eggs from Ameraucanas, Araucanas, and Cream Legbars; and green or olive eggs from Easter Eggers and Olive Eggers. Cream or tinted eggs come from breeds like Silkies and Faverolles. Shell color does not affect taste or nutrition.
Use the chart below to plan a flock that fills your basket with the colors you love.
One of the delights of a mixed flock is gathering a basket of eggs in different colors, from crisp white to deep chocolate, soft blue, and olive green. Shell color is entirely genetic, determined by the breed, so you can plan exactly the rainbow you want by choosing the right hens. The chart below groups popular breeds by the egg color they lay. Shades vary by individual bird and can fade over a long laying cycle, but every hen lays essentially one color for life.
Egg Color Chart by Breed
| Egg Color | Breeds That Lay It | Notes |
|---|---|---|
| White | White Leghorn, Polish, Ancona, Hamburg | Classic supermarket color; often from light Mediterranean breeds |
| Brown | Rhode Island Red, Australorp, Plymouth Rock, Sussex, Wyandotte, Orpington, sex-link hybrids | The most common backyard color; shades range from tan to medium brown |
| Dark chocolate brown | Marans (Black Copper), Welsummer, Barnevelder, Penedesenca | Deepest brown, often speckled; darkest early in the laying cycle |
| Blue | Ameraucana, Araucana, Cream Legbar | Pigment penetrates the whole shell, so blue inside and out |
| Green | Easter Egger | Blue gene plus brown pigment; color varies bird to bird |
| Olive | Olive Egger (blue-layer x dark-brown-layer cross) | Dark brown layered over blue produces rich olive green |
| Cream / lightly tinted | Silkie, Faverolles, Cochin, Brahma | Soft off-white to light tan; gentle pastel shades |
| Pink / plum bloom | Some Easter Eggers, Barred Rocks (light bloom) | A natural bloom coating can give a pinkish cast to some eggs |
The genetics are simple once you know them. Every egg starts white. A brown-egg breed adds surface pigment late in the process, which is why a dark egg can sometimes be gently rubbed lighter while the shell beneath stays pale. A blue-egg breed adds pigment early, so the color soaks through the whole shell. Cross a blue layer with a brown layer and the brown sits over the blue to make green or olive. That is the entire secret behind a colorful egg basket: choosing breeds with the right pigment genes.
Building a Rainbow Egg Basket
- White: Add a Leghorn or Polish for bright white eggs and high production.
- Brown: Most common breeds cover this, from Australorps to Plymouth Rocks.
- Dark chocolate: A Marans or Welsummer brings the deepest, often speckled brown.
- Blue: An Ameraucana or Cream Legbar adds true blue eggs.
- Green and olive: Easter Eggers and Olive Eggers round out the spectrum.
Remember that shell color is purely cosmetic: it does not change taste or nutrition, which depend on the hen's diet and forage instead. Choose your breeds for the colors that delight you and for the temperament and production traits that fit your flock. For breed selection or laying concerns, your local agricultural extension office and a poultry veterinarian are great resources. This chart is educational and a fun guide to planning your flock.

Frequently Asked Questions
What determines the color of a chicken egg?
Egg color is set by the hen's breed and genetics, not by her diet or environment. Every egg starts with a white shell, and pigments are added as it travels through the oviduct. Brown pigment (protoporphyrin) is applied on the surface late in the process, while blue pigment (oocyanin) is laid down early and penetrates the whole shell. A hen with both genes lays green or olive eggs. Because it is genetic, a given hen lays essentially the same color her whole life; you cannot change egg color by feeding her differently.
Which breeds lay blue eggs?
True blue eggs come from breeds carrying the blue egg gene, most notably the Ameraucana, the Araucana, and the Cream Legbar. Easter Eggers, which are mixed-breed birds carrying the blue gene, often lay blue or green eggs but can also lay other colors depending on their parentage. The blue pigment, oocyanin, penetrates the entire shell, so a blue egg is blue inside and out, unlike brown eggs where the color sits on the surface. Blue layers are popular for adding variety to the egg basket.
Which breeds lay the darkest brown eggs?
The darkest, chocolate-brown eggs come from Marans, especially the Black Copper Marans, and from Welsummers, whose eggs are dark brown and often speckled. Penedesenca and Barnevelder also lay deep brown eggs. The intensity varies by individual hen and tends to be darkest at the start of a laying cycle, fading somewhat as the season goes on before refreshing after a molt. Because brown pigment sits on the surface, you can sometimes gently rub a bit off a very dark egg, while the shell underneath is pale.
Do different colored eggs taste different?
No. Shell color has no effect on the taste or nutrition of the egg inside. A blue, brown, white, or green egg from hens kept the same way will taste and nourish the same. What actually changes flavor and nutrition is the hen's diet and access to forage: pasture-raised hens eating greens and insects often produce eggs with deeper yellow-orange yolks and richer flavor, regardless of shell color. So choose breeds for the egg colors you enjoy looking at, but do not expect a taste difference from the shell.
Can one hen lay different colored eggs?
No. An individual hen lays one shell color her entire life, determined by her genetics. What can vary slightly is the shade and the amount of speckling or bloom from egg to egg, and very dark brown eggs may fade a bit over a long laying cycle, but the underlying color stays the same. If your basket shows several colors, that is because you have different breeds. A single hen will not switch from brown to blue, though her eggs may look a touch lighter or darker day to day.
What are olive egger chickens?
Olive Eggers are crossbred chickens created by breeding a blue-egg-laying bird (such as an Ameraucana) with a dark-brown-egg-laying bird (such as a Marans or Welsummer). The chick inherits both the blue gene and heavy brown pigment, and the brown layered over blue produces a distinctive olive-green egg. The exact shade varies with the specific cross. Olive Eggers are not a recognized breed but a deliberate hybrid prized for their unusual eggs, much like Easter Eggers, and they are a favorite for keepers wanting a colorful egg basket.
Why are my hen's eggs getting lighter in color?
Fading is normal, especially in breeds that lay dark brown eggs. The brown pigment is applied to the shell surface, and a hen has a finite amount of pigment to dispense across a laying cycle, so eggs are often darkest early and lighten as the cycle continues. After a molt and rest, the color typically refreshes. Age, stress, heat, and illness can also lighten or alter shell color and quality. A gradual seasonal fade is expected, but a sudden change in color or shell quality across the flock is worth investigating.
