French Black Copper Marans (Alchemist Line)

We are really excited about our Marans for the 2025 breeding program. After 10 years of tinkering we believe we have finally found the perfect balance of stunning dark chocolate egg color, high production, lovely temperament and beauty. Every year just gets better and better with this breed.

The roosters are excellent at protecting the flock and making sure the hens fall back to the coop if a predator enters the barnyard from the land or sky.

The marans egg is always the egg that will stop people in their tracks when they look at a dozen. The color and quality of the eggs that our marans lay is one of the many things that makes our breeding program stand out in comparison to larger hatcheries. You will not be disappointed by the look of both the birds and eggs of this breed. In the last few years some of the girls have begun to lay eggs with heavy blooms over the top to create the appearance of a purple or pink egg like the one in the top right of this photo. Hens laying in this color/bloom will be a fun surprise in your egg basket if you receive one as a chick. Less than 10% of our adults grow up to lay in this shade but when they do it is fascinating to see.

Our girls and boys are all feathered on shake and their outside toes. 90% of our females have nice copper expression in their necks and all have an excellent disposition. Our 2025 Alchemist Line of French Black Copper Marans a completely new line from our previous years releases. If you are looking for more genetic diversity from the birds you have received from us in the past – look no further! We have been perfecting this line for 10 years and 2025 is the best release yet!

This breed cannot be sexed as chicks, they are sold straight run which means each chick has a 50/50 chance of being male or female.

In height of production our girls lay 5 eggs a week that are at least a 6 on the egg color chart.

We are particularly fond of our Marans roosters who are stunning, laid back and trustworthy. Our roosters faithfully protect our hens and always give them the first chance at food.

Whenever we gift a dozen mixed rainbow eggs to a friend they always comment on the Marans eggs first because of their beauty and size. The quality of their egg overall is superior to that of other breeds in that the shells are thick and the yolks are extra dense. When cracked open, the yolk of our free-range birds is bright orange, bursting with vitamins, protein and fats from the extra time it took to lay the egg. While a typical store-bought egg has a yolk that is runny and flaccid, the free-range Marans produce yolks that have ‘muscle tone;’ little orange domes that jut skyward from the egg white. You can taste the difference!

More on the back story of this breed:

The Black Copper Marans chicken is a breed of domestic fowl that originated in France. The breed was developed in the town of Marans, located in the Charente-Maritime region of France, in the late 19th and early 20th centuries. The breed was originally used for both egg production and meat, and it was prized for its rich, dark brown eggs.

In the early 20th century, the breed became popular among French poultry fanciers, who worked to standardize its appearance and improve its egg-laying ability. By the 1920s, the Black Copper Marans had become one of the most highly prized breeds of poultry in France, and it was soon exported to other countries, including England and the United States.

In the United States, the Black Copper Marans remained a relatively obscure breed until the late 20th and early 21st centuries, when a growing interest in heritage poultry breeds led to a resurgence of popularity for the breed. Today, the Black Copper Marans is widely recognized as a high-quality layer of rich, dark brown eggs, its attractive appearance, and its gentle, docile temperament.

The world’s darkest chocolate-brown eggs — bred carefully at our farm for over a decade years.

Our French Black Copper Marans lay the world’s darkest brown eggs — eggs that score at minimum a 6 on the Marans color chart at peak production, with most of our flock hitting 7s and the occasional hen producing an 9. They’re feather-shanked in the proper French style, 90% of our females show copper expression in the neck, and after ten years of careful breeding our 2026 line is the strongest it’s ever been.

What Makes Our French Black Copper Marans (Alchemist Line) Different

• Ten years of selective breeding for egg color, temperament, and copper expression.
• Properly feather-shanked — distinguishes our line from American clean-legged Marans.
• 90% of females show copper-orange neck expression — a sign of preserved Black Copper genetics.
• Minimum 6 on the Marans color chart at peak production. Most hens lay 7s.
• ~10% of hens grow up to produce eggs with a heavy purple/pink/plum bloom — a small lottery you opt into.
• 2026 line introduces fresh blood from out-of-state bloodlines we hand-selected.

Care Basics

• Feather-shanked legs need to stay reasonably dry — Marans don’t thrive in chronically muddy runs. Well-drained bedding is important.
• Plan on 4 sq ft of coop per hen and 10+ sq ft of run. They’re larger birds and need space.
• Cold-hardy — handles freezing weather without much management.
• In hot climates, deep shade and shallow water for foot-cooling. Reduce scratch grains in summer.
• See our complete brooder protocol in the New Chicken Keepers guide.

Common Questions

How dark are Alchemist Farm Marans eggs?

Minimum 6 on the Marans color chart at peak production. The majority of our flock lays 7s. Occasional hens produce 9s. We do not breed hens whose eggs score below a 6.

Why are some of the eggs purple or pink?

Some of our hens grow up to produce eggs with an unusually heavy bloom — the natural protective coating on every egg. Heavy bloom can make an egg appear purple, pink, or plum until it’s washed. Less than 10% of our hens lay in this color range, so it’s a small lottery when you order chicks from us.

Can Marans be sexed at hatch?

No. Marans cannot be reliably visually sexed as chicks. They’re sold straight run with a 50/50 male/female ratio.

Why are these more expensive than typical hatchery Marans?

Because they’re better. Production-line American Marans (the kind sold at the largest hatcheries) typically lay eggs scoring 3-5 on the chart — meaningfully lighter than what serious Marans keepers want. Our line is the result of ten years of selective breeding for the deep color and proper French body type.
