What color egg does Blue Cuckoo Maran lay?


The Blue Cuckoo Maran is a rare and unique chicken breed known for laying beautiful chocolate-colored eggs. This breeds originates from France and was first imported to the United Kingdom and North America in the early 1900s. The Blue Cuckoo Maran has since gained popularity among backyard chicken keepers and small farmers for its gorgeous plumage and egg color. But what exactly causes Marans to lay such dark, chocolate-colored eggs? And what color eggs specifically do Blue Cuckoo Marans lay?

Marans are Known for Laying Dark Brown Eggs

The Marans breed is well known for laying some of the darkest brown eggs of any chicken breed. Most Marans lay eggs that are a very deep chocolate brown color. The dark egg color is caused by a genetic factor that results in the chickens producing eggs with an especially high concentration of pigment. This gives the egg yolk and shell a rich, dark color.

While the exact color intensity may vary somewhat between individual hens, Marans are unique in their ability to produce such dark brown eggs consistently. Other chicken breeds that lay brown eggs typically produce a much lighter brown color. The exceptionally dark eggs are a hallmark trait of the Marans breed.

Factors that Influence Marans Egg Color

While all Marans lay dark brown eggs, there are some factors that can impact the specific color intensity:

– Genetics – Some Marans bloodlines tend to lay darker eggs than others. Breeding can intensify the depth of brown color.

– Diet – Access to green forage, like grass or vegetables, enhances pigment levels.

– Age of the hen – Younger Marans hens usually lay darker eggs, with color fading somewhat as they age.

Because of these factors, the exact shade of brown of a Marans egg can range from chocolate to copper to a darker tan. But they will consistently be far darker than eggs from other brown egg layer breeds.
