Marans are very outgoing, lively and yet somewhat shy animals, some can also develop a slightly combative character. In breeding, in addition to the physique and plumage, attention is paid to the darkest possible coloration of the eggs. The laying performance is about 180 to 200 eggs per year. The minimum weight of hatching eggs is 65 g. The rooster has a weight of 3.5-4 kg and the hen 2.5-3 kg.

A characteristic of this breed of chickens are the light to dark brown eggs, which can be covered with dark spots and whose color becomes lighter during the year. In the course of the laying year the eggs lighten more and more, they are then still rich brown, partly with slightly darker spots, but not quite as dark as at the beginning. With the beginning of the next laying period the eggs start again as dark as the year before. Another characteristic of these eggs is their very thick shell, which makes evaporation of liquid and penetration of germs difficult. This means that they can not only be stored for a very long time, but may also be suitable for hatching months later. Best Race Ever i love My Marans
