Historical origin of the breed

Mericanel della Brianza breed has probably originated from crossbreeding of local breeds with Asian bantam breeds introduced to Northern Italy in the 1600s up to last century.
In those years, trades were frequent also in agriculture and breeding; trading with merchants from Venice, facilitated by closeness, was probably the way that brought Asian bantam chickens to Northern Italy, thus leading to the diffusion of small-sized breeds such as Pepoi in Veneto and Mericanel della Brianza in Lombardy.
The breed is named after its geographical area of origin, Brianza, an hilly region lying north-east of Milan, and including the provinces of Monza-Brianza, Lecco, Como, and a small part of the province of Milan. It is supposed that the name “Mericanel” comes from a Brianza dialect word for “american”, thinking by mistake that the breed originated in America, or from the Brianza name “mericanel”, used for particularly lively children.

At the beginning of the XX century, MB chicken were present in small rural farms as free-range chickens. In the XIX and XX centuries, Brianza was a rural land, where people’s sustenance used to come from sharecropping; in such a context, poultry was not foraged, apart from capons only, intended for the bourgeioisie. MB chickens, therefore, used to live free around the farms, without either any care about their food or about livery selection.

MB chickens are well proportioned, round-shaped, and elegant, but have also a strong temperament. It is a rural breed, that prefers to stay in the open; it is very lively, not demanding, and able to find food (insects, fruit, and other plants) in the wild to satisfy its nutritional needs; it has a wild nature and a good flying ability that allows chickens to reach the higher branches of the trees, up to 12-15 meters from the ground. Hens have an excellent brooding aptitude and are excellent mothers, exemplary in defending and leading the offspring.
The breed has never been selected on the basis of liveries, but rather based on other properties such as rusticity, small size, and yellow skin shanks.

MB belongs to dwarf or bantam breeds, frequently categorised in the past as “fancy birds”. The small size of birds and eggs made them unsuitable as food, so they were reared mainly for decorative purposes. At the begining of the 1900, some authors claimed that bantam chicken breeds shouldn’t even be included into poultry management books, being used only for fancy, not productive, purposes. However, their high brooding aptitude, also towards eggs belonging to other species (i.e. game birds), the ease of breeding, and their strong scratching activity, helpful for the house keeping of the courtyard in the villas, guaranteed their survival.

Feather distribution: Normal

Plumage structure: Stiff, abundant with wide feathers

Plumage colours:
Most frequent colours: White, Black mottled, Gold
Other colours: Black, White gold, Silver

Colour features:
Single colour, without sexual dimorphism: White, Black
Bi-colour, without sexual dimorphism: Black mottled
Bi-colour, with sexual dimorphism: Gold, Silver, White gold

Colour pattern:
White – Pure white, more brilliant in the male. White down.

Black – Intense black, with strong brilliant green sheen in the male. Grey to black down, even lighter in the male.

Black mottled – Brilliant black plumage with green sheen. Several feathers have white spots at the tips, preferably V-shaped. Mottling must be as uniform as possible. Spots at the tips of flights, sickles and hackle feathers have to be considered a merit. In the male, the pattern is less marked than in the female, thus it appears to be darker; one to four white primaries are permitted. Thin blackish streaks on the shanks permitted. Down ash-grey to grey.
