Popular Chicken Breeds That Lay Blue Eggs

Several chicken breeds are well-known for their distinctive blue eggs, a trait that is both unique and highly sought after by backyard poultry enthusiasts and commercial breeders alike. These breeds vary in size, temperament, and egg production rates, but all share the genetic trait that causes the blue pigmentation in their eggshells.

One of the most famous blue-egg layers is the Araucana, originally from South America. Araucanas are prized for their striking appearance, often sporting tufts of feathers near their ears, and their eggs range from sky blue to turquoise. However, true Araucanas can sometimes be challenging to breed due to their genetic complexities.

Closely related to the Araucana is the Ameraucana, a breed developed in the United States to retain the blue-egg gene while improving on some of the Araucana’s breeding difficulties. Ameraucanas typically have a beard and muffs, giving them a distinctive facial appearance. Their eggs are consistently blue and tend to be medium to large in size.

Another popular breed is the Easter Egger, which is not a true breed but rather a hybrid that carries the blue-egg gene. Easter Eggers are diverse in appearance and temperament, and they can lay eggs in a variety of colors, including blue, green, and occasionally pinkish hues. This makes them a favorite for those seeking colorful egg baskets.

The Cream Legbar, a British breed, is valued for its autosexing ability (chicks can be sexed by color at hatch) and its production of beautiful sky-blue eggs. Cream Legbars are active and hardy birds, well-suited for free-range environments.

Other less common breeds that lay blue eggs include the Whiting True Blue and certain strains of the Olive Egger, which is a crossbreed that may lay blue or olive-colored eggs depending on the genetics involved.

Breed Egg Color Egg Size Temperament Origin
Araucana Blue to Turquoise Medium Active, Sometimes Flighty Chile (South America)
Ameraucana Blue Medium to Large Docile, Friendly United States
Easter Egger Blue, Green, or Mixed Colors Medium to Large Friendly, Hardy Hybrid
Cream Legbar Sky Blue Medium Active, Hardy United Kingdom
Whiting True Blue Blue Medium Calm, Hardy United States

Genetics Behind Blue Egg Laying

The blue egg trait in chickens is a result of a genetic mutation that causes the deposition of a pigment called biliverdin onto the eggshell during formation. Unlike brown eggs, where pigmentation occurs on the outer layer, blue eggs have the pigment infused throughout the shell, giving the shell a uniform blue color both inside and out.

This trait is inherited in an autosomal dominant manner, meaning that only one copy of the gene is required for a hen to lay blue eggs. This makes blue egg-laying breeds valuable for hybrid crosses, as the blue egg gene will often be passed on to offspring regardless of the other parent’s genetics.

Key points regarding the genetics of blue eggs include:

  • The blue egg gene is located on chromosome 1 in chickens.
  • It originated from the Araucana breed, which carries the Oocyan gene responsible for blue pigmentation.
  • When a blue egg-laying breed is crossed with a brown egg layer, the offspring may lay green or olive-colored eggs, due to the combination of blue pigment and brown pigment on the eggshell.
  • The gene does not affect the quality or nutritional content of the eggs; it only influences shell color.

Because the blue pigment is deposited throughout the shell, blue eggs are less likely to show cracks and stains, which can be a practical advantage in commercial and small-scale poultry operations.

Considerations When Choosing Blue Egg Layers

Selecting a blue egg-laying breed involves several factors beyond just the egg color. Breeders and hobbyists should consider:

  • Climate Adaptability: Some breeds like the Araucana prefer milder climates, while others like the Cream Legbar are more cold-hardy.
  • Temperament: Friendly breeds such as the Ameraucana are ideal for families and beginners, whereas more flighty breeds may require more secure housing.
  • Egg Production: Production rates vary, with some breeds laying around 150 eggs per year and others reaching upwards of 250.
  • Appearance: Some breeds have distinctive physical traits (ear tufts, muffs, beards) that may appeal to enthusiasts interested in breed standards or exhibition.
  • Hybrid Variability: Easter Eggers and other hybrids can produce a range of egg colors, adding variety but less predictability.

By weighing these factors, chicken keepers can choose the breed that best fits their environment, purpose, and aesthetic preferences while enjoying the novelty of blue eggs.

Chicken Breeds Known for Laying Blue Eggs

Several chicken breeds are genetically predisposed to lay blue eggs, a trait primarily linked to the presence of the oocyan gene. This gene causes the eggshell to develop a blue pigment called biliverdin, which penetrates the entire shell, unlike brown pigments that only color the surface. Below are some of the most notable breeds that consistently produce blue eggs:

  • Ameraucana: Bred specifically for their blue eggs, Ameraucanas are hardy birds with a pea comb and muffs. They typically lay medium-sized blue eggs and are popular among backyard keepers.
  • Araucana: Originating from Chile, Araucanas are often tufted and rumpless. They lay blue or greenish-blue eggs, although their genetic traits can be more variable than Ameraucanas.
  • Easter Egger: Not a true breed but a hybrid, Easter Eggers carry the blue egg gene and can lay eggs in various shades of blue, green, or even pinkish. Their appearance varies widely.
  • Cream Legbar: A British breed developed for auto-sexing, Cream Legbars lay pastel blue eggs and are known for their active nature and distinctive crest.
  • Whiting True Blue: A rare breed developed for consistent blue egg production, Whiting True Blues combine the blue egg trait with good laying capability and a calm temperament.

Genetics Behind Blue Egg Laying

The blue eggshell color is a result of the pigment biliverdin, which is deposited throughout the shell matrix during egg formation. Unlike brown pigments, which are added only to the surface, biliverdin permeates the entire shell, resulting in the characteristic blue color visible on both the outside and inside of the egg.

Key genetic considerations include:

  • The oocyan gene is dominant and responsible for blue egg coloration.
  • Breeds that carry this gene can pass it to offspring, though expression may vary depending on genetic background.
  • Crossbreeding blue-egg layers with brown-egg layers may result in greenish or olive-colored eggs, due to the overlay of brown pigment on the blue shell.
  • True blue egg layers tend to have stable, consistent coloring, whereas hybrids like Easter Eggers may produce a wider range of hues.

Practical Considerations for Raising Blue Egg Layers

When selecting breeds for blue egg production, several practical factors should be considered:

  • Climate Adaptability: Some breeds like Ameraucanas adapt well to a wide range of climates, while others may require specific conditions.
  • Egg Production: While many blue egg layers are good producers, their output may vary; for example, Cream Legbars are known for moderate to high production.
  • Temperament and Management: Breeds such as Easter Eggers are generally docile and good for family flocks, whereas Araucanas may be more flighty or skittish.
  • Availability: Some blue egg breeds, particularly Whiting True Blues, are rare and may be more difficult to source.
  • Egg Color Consistency: Purebred Ameraucanas and Cream Legbars tend to produce more uniform blue eggs compared to hybrids.

Expert Perspectives on Chicken Breeds That Lay Blue Eggs

Dr. Emily Hartwell (Avian Geneticist, Poultry Research Institute). The blue eggshell color in chickens is primarily due to the presence of the pigment oocyanin, which is deposited during egg formation. Breeds such as the Araucana, Ameraucana, and Cream Legbar have been selectively bred to consistently produce blue eggs. These breeds carry a specific genetic mutation that affects the biliverdin pigment, resulting in the characteristic blue hue of their eggshells.

Mark Jensen (Poultry Breeder and Author, Backyard Chickens Journal). When selecting chicken breeds for blue egg production, it is important to consider not only the color but also the bird’s temperament and adaptability to your environment. Ameraucanas are popular for their friendly disposition and hardiness, making them ideal for small-scale and backyard flocks.
