Marans chicken: size, eggs and care guide

The Marans is a standard-size breed laying about 150 to 200 dark chocolate brown eggs a year, with hens around 6.5 lb and roosters around 8 lb. The dark pigment is a coating applied in the shell gland, not part of the shell. You can literally rub some of it off a fresh Marans egg with a damp cloth, which is a good party trick and a useful way to spot a genuinely dark layer.

How big is a Marans?

A mature Marans hen weighs about 6.5 lb and a rooster about 8 lb, with a typical standing height of 15 to 17 inches. That puts it in the standard class, which is what drives its feed requirement of roughly 0.25 lb per bird per day before waste, free-ranging or seasonal adjustments.

Marans egg production

Eggs are not this breed's main strength. A Marans lays around 150 to 200 large dark chocolate brown eggs a year, about 2.9 to 3.8 a week, so it is usually kept for other qualities and the eggs treated as a bonus. Output drops further during the moult and the darkest weeks of winter. To turn that into a monthly total and a dollar value at your local egg price, run it through the egg production calculator.

Temperament and noise

Quiet and calm, generally undemanding, with a slightly more reserved manner than a Sussex or Rock. Not a lap bird, but not flighty either. Noise level is rated quiet, which matters if you keep chickens close to neighbours.

Origin and history

From the marshland town of Marans on the French Atlantic coast, where local birds were crossed with fighting stock brought in by sea. France codified it in 1921 and the breed built its reputation entirely on egg colour, to the point that French standards grade Marans eggs on a numbered darkness scale.

Cold and heat tolerance

Cold tolerance is good and heat tolerance good. The upright single comb is the part most at risk in hard freezes, so ventilation that removes moisture without creating a draft matters.

Does the Marans go broody?

Sometimes. A broody hen stops laying and sits, which is a nuisance if you want eggs and a gift if you want chicks hatched naturally without an incubator.

Care specifics for this breed

Straightforward, though the darkest-laying strains are often the least productive, so you are choosing between colour and count. Egg colour also fades across a laying cycle, darkest at the start after a moult and lighter by the end.

Feed cost for a flock of Marans

Feed cost sits in the normal range for a standard laying breed: about 0.25 lb per bird per day, so six Marans birds come to roughly $21.19 a month at $22 per 50 lb bag. Free-ranging typically trims around 15% off that and winter adds about 10%. The feed cost calculator gives the exact figure for your flock size and local feed price, including bags needed and how long each lasts.

Is the Marans right for you?

It suits keepers who want the darkest brown eggs available and will accept a moderate laying rate for them. It is a weaker choice for anyone prioritising egg count, or unwilling to pay a premium for good stock.
