Our pretty infographics make complex chicken egg color breeding simple to comprehend! Children, teens, and beginners will find introductory genetics easily explained in visual format, which helps breeding projects go exactly as planned. Let’s jump into our beautifully simple chicken breeding recipes:
Chicken Breeding Recipes for Creating Colored Egg Layers
Chicken egg color genetics are complex. This article is meant to serve as a visually simple guide for beginner 4-H, FFA and school age youth who are interested in breeding colored egg layers. The large and simplified infographics below explain basic egg shell color inheritance. The breeding recipe cards that follow help students plan what rooster and hens to cross to get the egg colors they desire.
Understanding Basic Egg Shell Color Genetics
No matter how many colors and shades eggs come in, the underlying shell can only be either blue or white. Every other egg color is made by varying amounts of tint being laid over these two shell colors. Blue is dominant so if a hen inherits a single blue egg gene, she will produce blue egg shells. White is recessive so a hen needs to inherit two copies of recessive white to have white egg shells (both white and all shades of brown laying hens carry two copies of recessive white egg shell genes).

Tint Overlay Shades Can Vary
How Tint Overlays Make Green Eggs
Let’s Begin Breeding Colored Egg Layers!
Now that you understand what egg shell base colors and tint overlay colors combine to make different eggs, let’s follow some breeding recipes to create colored egg laying hens:
The graphics below illustrate what you can expect when using a single rooster to produce offspring from various colored egg laying hens.
How to Breed Guaranteed Blue Egg Layers
Easter Eggers are a hybrid, which means they are a mix of different chicken breeds. “Homozygous” means the bird carries two copies of one gene, in this case the blue egg gene. Homozygous blue egg gene roosters are often purebred Whiting True Blue, true Ameraucana (from a specialized breeder) or Crested Cream Legbars. You can mate these purebred roosters to any hen and the offspring will always lay blue or green eggs because chicks will always inherit one copy of the dominant blue egg gene from their father. (Remember, blue egg shells are dominant so if a hen inherits just one copy, she will produce blue egg shells!)
How to Breed Blue & Green Egg Laying Easter Eggers
Using the Same Rooster to Breed Olive Eggers
If you breed the same homozygous blue egg gene rooster to hens who lay darker brown eggs, you’ll get first generation, Filial 1 (F1) Olive Eggers!
Why are Light Olive and Sage Tones Expected? Because your rooster is carrying NO tint genes at all, the chicks only inherit tint genes from the mother. This tends to “lighten” the tints so the offspring lay light olive and sage eggs, not dark olive eggs.
How to Breed Olive Eggers (the most popular way)
Most people like to use a dark egg line rooster, such as a Black Copper Marans, bred to blue egg laying hens to produce olive eggers. Why? Because they want to use the same rooster the next year to darken the eggs! Doing this is called back-crossing and it makes olive eggs darker:
How to Back-Cross Olive Eggers
How to Breed Speckled Olive Eggers
You can attempt to breed speckled olive eggers by using a rooster who comes from a speckled egg line. Many Marans and purebred Welsummers have speckled shells and are good roosters to use for this project. Remember, this is an attempt to breed for speckled olive eggs; speckling is never guaranteed to be present on the offspring’s egg shells.
Another Speckled Olive Egger Recipe
You can attempt to breed speckled olive eggers using a homozygous blue egg gene rooster and speckled brown laying hens. Only hatch from the most heavily speckled eggs for the best chance of offspring who lays eggs with speckling!
Breeding Classic Easter Eggers
This is how hatcheries breed their popular Americana/Easter Egger chicks! If you want to be able to produce blue, green, and peach egg layers using only one rooster, he needs to be heterozygous for the blue egg gene. This means he carries one dominant blue egg gene and one recessive white egg gene.
How Do I get a Heterozygous Blue Roo? You can guarantee you get a heterozygous blue rooster if he hatches from a white egg fertilized by a homozygous blue egg rooster.

What if I Just Use an Easter Egger Roo I Already Have?
This can be a lot of fun and a great way for everyone to learn about chicken genetics. You won’t know what egg color genes your rooster carries until his daughters begin laying, and then you can make an educated guess! Here are some breeding recipes to help you know what to expect:

Oh my. I LOVE these — they’re SO helpful! Thanks in part to this site, I’ve realized that selling hatching eggs and getting beautiful chicken eggs to bring to market *isn’t* such a far fetched notion I’ve dreamed of! Thank you for all the time you’ve put into all of this! It’s been EXTREMELY helpful to me . . . and my family and I’ve been keeping chickens for nearly 18 years, now!
