The Ancona chicken is an Italian breed, taking its name from the city and province of Ancona in the Marche region. Although its origins are Italian, the breed was developed into its modern form largely in the United Kingdom during the 1800s. By 2025, its global conservation status was listed as "at risk," with just over 800 birds reported worldwide—most of them in Australia. A bantam version also exists.

This breed comes from central Italy, where it was once the most widespread chicken. In 1851, some birds were sent to England, where breeders worked to make the white markings on the feathers more regular and consistent. A breeder named Cobb exhibited a group in 1880. Birds were later exported from Britain to the United States in 1888. The rose-combed variety was first shown in Birmingham, England, in 1910. The American Poultry Association recognized the single-combed Ancona in 1898 and the rose-combed version in 1914.

The Ancona is a typical Mediterranean chicken: hardy, active, and lively. It roams widely and can take flight easily. Its plumage is black with white mottling—about one feather in three has a white V-shaped tip. All primary flight feathers, sickles, and tail feathers should have white tips, and the black feathers may show a beetle-green sheen. In Italy, a blue mottled with white variety is accepted for full-sized birds but not for bantams. Australia recognizes a red variety with a chestnut to red-bay ground color. The legs are yellow with black mottling, the beak is yellow with some black on the upper mandible, and the eyes are orange-red. Skin is yellow, and ear-lobes are white or cream. The comb is medium-sized with five distinct points; in hens, it falls gracefully to one side. In the UK and US, but not Italy, a rose comb is also allowed. Cocks weigh 2.5 to 2.8 kg, hens 1.8 to 2.1 kg. Ring sizes are 18 mm for cocks and 16 mm for hens in full-sized birds, and 13 mm and 11 mm for bantams.

The Ancona is a good layer, producing about 220 white eggs per year, each weighing 50 grams or more. Hens rarely go broody, and pullets may start laying at five months old.

Lore & Background

The Ancona originated in central Italy, where it was the breed of chicken with the widest distribution. Some birds were exported in 1851 to England, where they were selectively bred for regularity and consistency of the white markings in the plumage. In 1880 a breeder named Cobb showed a group. Some were exported from Britain to the United States in 1888. Rose-combed Ancona chickens were first shown in Birmingham, in the West Midlands, in 1910.

Reader's Guide

The Ancona chicken represents a notable example of how a regional Italian breed was transformed through selective breeding in the United Kingdom during the nineteenth century. Its name derives from the city and province of Ancona, but its present type was largely established in Britain, where breeders focused on standardizing the white mottling in the plumage. The breed's conservation status in 2025 was 'at risk', with only about 800 birds reported worldwide, most in Australia. In Italy numbers are very low; an initiative to re-establish the breed in its native area and to preserve its biodiversity was launched in 2000. The Ancona is a typical Mediterranean chicken—rustic, lively, and hardy—and is a good layer of white eggs, averaging 220 per year. Its plumage is black mottled with white, with approximately one feather in three having a v-shaped white marking at the tip. The breed's significance lies in its dual heritage: Italian origin and British refinement, and in the ongoing conservation efforts to prevent its extinction.
