the french lines will have feathered legs as for the british and american lines it has basiclly been breed out of them...
This breed, which originated in western France in the town of Marans, is best known for its dark chocolate colored eggs. It is a fast grower and does well in damp areas, having been developed in a marshy portion of France. The original French birds have feathered legs, but this characteristic has been bred out of the British and many American line. The French recognize 8 varieties: 1. Silver Cuckoo, 2. Golden Cuckoo, 3. White, 4. Coppered Black, 5. Black, 6. Wheat, 7. Black-tailed Fawn, and 8. Ermine; they are considering adding the Silvered Black (created since 1932 and remarkable for the color and spherical form of its eggs). In the Cuckoo Marans, males are lighter in color than females--it is said to be possible to color sex them even as chicks with pretty good accuracy. I've never seen or heard about the other varieties.
