French Black Copper Marans chicks grow into striking, heavy-bodied birds best known for their exceptionally dark chocolate-brown eggs—some of the darkest of any chicken breed. Hens are steady layers, typically producing around 150–200 large eggs per year, prized for both their rich color and quality. They generally reach laying maturity at about 20–24 weeks of age. These birds feature beautiful black plumage with a greenish sheen in sunlight. French Black Copper Marans are known for their calm, gentle, and easy going temperament. They tend to be quiet birds that do well in mixed flocks and are a great option for backyard keepers. Hardy and adaptable, they handle a variety of climates well and are especially valued by those looking for both unique egg color and a docile, manageable bird.
