Rainbow Eggs: Why Chickens Lay Different Colored Eggs

The science behind the beautiful eggs from Serenity Hill Flower Farm

If you've ever opened a carton of farm-fresh eggs and discovered blues, greens, creams, and deep chocolate browns inside, you might wonder:

Why do chickens lay different colored eggs?

At Serenity Hill Flower Farm, our hens produce a rainbow of eggs every day. These beautiful colors aren’t from dyes or special feed — they come directly from the breed of chicken.

Some of our rainbow color eggs.

Just like flowers bloom in different colors depending on the variety, different chicken breeds naturally lay eggs in different shades.

Let’s meet a few of our favorite egg-laying hens.

Black Copper Marans

Famous for their dark chocolate eggs

One of the most stunning eggs in the chicken world comes from the Black Copper Marans.

This French breed lays farm-fresh eggs sometimes so dark they look almost mahogany.

The color comes from a natural pigment called protoporphyrin, which coats the shell just before the egg is laid.

Black Copper Marans are also known for their calm personalities and cold-hardy nature — perfect for farms here in northern Illinois.

Cream Legbars

The hens that lay beautiful blue eggs

If you’ve ever seen a farm-fresh eggs chances are it came from a Cream Legbar.

These cheerful hens lay eggs colored by a pigment called biliverdin, which is incorporated directly into the shell as it forms. Because of this, blue eggs are blue all the way through the shell, not just on the surface.

Cream Legbars are easy to recognize thanks to the adorable feather crest on top of their heads.

Nothing like a beauty of bright blue eggs here from our happy hens.

Easter Eggers

The surprise egg artists

Perhaps the most fun chickens in our flock are the Easter Eggers.

These birds carry the blue egg gene but are mixed genetics, which means their eggs can appear in many shades, including:

• Soft blue

• Sage green

• Olive

• Pale turquoise

• Pink-tinted cream

Each hen lays the same color egg throughout her life, but the color can vary from hen to hen.

They’re friendly, curious birds and one of the reasons our egg cartons look like little rainbow palettes.

What Determines Egg Color?

The color of an eggshell comes from pigments deposited during egg formation in the hen’s reproductive tract.

Two main pigments are responsible:

• Biliverdin → creates blue or green eggs

• Protoporphyrin → creates brown eggs

Sometimes the pigments combine. For example: Olive eggs = blue shell + brown coating

Despite their different colors, all eggs have similar nutrition. The rich golden yolks often seen in farm eggs come from a varied diet of greens, insects, grains, and sunshine.

A Rainbow From the Nest Box

One of the simple joys of farm life is collecting eggs each morning and seeing the variety our hens create.

Some mornings the basket holds pale blues and sage greens.Other days it’s chocolate browns next to soft creams.

Every egg tells the story of a different hen in the flock — and together they create a small rainbow from the coop.

At Serenity Hill Flower Farm, our eggs come from happy free-range hens, and that difference shows in both color and flavor.
