The Andalusian Bantam is the striking miniature of a classic Spanish breed, known for its beautiful slate-blue, laced plumage and its reputation as a prolific layer of white eggs. Active, alert, and a fantastic forager, it is best known for its unique blue color genetics.

Characteristics

The Andalusian Bantam is a graceful, slender bird of the Mediterranean type, known for its active and alert posture. They are well-balanced with a long, sloping back and a proud carriage.

  • Weight: Roosters typically weigh 1.75 - 2.0 lbs (800-900g), with hens weighing slightly less at 1.5 - 1.75 lbs (700-800g).
  • Comb: The breed has a single comb, which should be large and bright red with five or six distinct points. On the rooster, it stands upright, while on the hen, it gracefully droops to one side.
  • Earlobes: A key feature is their smooth, white, almond-shaped earlobes.
  • Legs and Feet: Their legs are clean and slate-blue in color.
  • Temperament: Andalusians are quintessential foragers. They are active, busy, and can be quite noisy. While not typically a docile lap chicken, their curious and industrious nature makes them fascinating to watch in a free-range setting.

Egg Laying

True to their Mediterranean heritage, Andalusian Bantams are excellent egg layers. They are highly valued for their consistent production and rarely go broody, making them a very practical choice for those wanting a steady supply of small eggs.

  • Egg Production: Hens can lay around 180 large white eggs per year.
  • Egg Size & Color: The eggs are a good size for a bantam, averaging 1.4 oz (40g), and are a classic chalk white.
  • Broodiness: This is a non-broody breed. Hens will lay consistently through the season without the interruption of wanting to sit on a nest.

Hen vs Rooster

Apart from the rooster being larger with more developed hackle and sickle feathers, the most obvious difference is the comb. A mature rooster will have a large, firm, upright single comb. In contrast, the hen's comb is also large but will lop, or fold over, to one side. This 'lopped' comb is a classic characteristic of Mediterranean laying hens and should not be considered a fault.

Climate and Housing

The Andalusian is a hardy breed that can adapt to various climates. Their active nature and lighter build make them quite heat-tolerant. While they can also handle cold weather, their large single combs are susceptible to frostbite in freezing temperatures. A dry, well-ventilated, and draft-free coop is essential to protect them during harsh winters.

Due to their active and flighty disposition, they are not well-suited for close confinement. They are happiest when allowed to free-range or in a large, secure run where they have ample space to forage and explore.

Color Varieties

The Andalusian is famous for its unique slate-blue plumage. While only one color is recognized for exhibition, breeding this color inherently produces two other variants that are crucial to the breed's genetics.

  • Blue (Laced): The standard and most desired color. It consists of a medium slate-blue ground color, with each feather edged in a darker, more lustrous lacing. The rooster's hackle and saddle feathers are a rich, lustrous black.
  • Black: A solid, glossy black that results from the blue color genetics.
  • Splash: A white or off-white ground color with irregular 'splashes' of slate-blue across the plumage.

History of the Andalusian Bantam

The Andalusian chicken originates from the Andalusia region of Spain, where it was developed as a local landrace. It was first imported into England in the 1840s and 1850s, where breeders refined the breed and standardized its unique blue-laced coloration. The breed quickly gained popularity for its beauty and productivity and was included in the first American Standard of Perfection in 1874.

The bantam version was created later, likely in the early 20th century in either Great Britain or Germany. Breeders miniaturized the large fowl while carefully preserving its distinct type, active temperament, and, most importantly, its unique blue color genetics.

The Genetics of Blue

A Classic Example of Incomplete Dominance

The Andalusian's slate-blue color is a textbook example of incomplete dominance in genetics. The gene responsible is the Blue gene (Bl).

  • A bird with one copy of the Blue gene and one copy of the black gene (Bl/bl+) will be Blue.
  • A bird with two copies of the black gene (bl+/bl+) will be Black.
  • A bird with two copies of the Blue gene (Bl/Bl) will be Splash (blue-splashed white).

Because the Blue color is heterozygous, breeding two Blue birds together will not result in 100% Blue offspring. According to Mendelian genetics, a Blue x Blue cross will produce, on average:

  • 50% Blue (Bl/bl+)
  • 25% Black (bl+/bl+)
  • 25% Splash (Bl/Bl)

To produce 100% Blue offspring, a breeder must cross a Black bird with a Splash bird. This genetic quirk is a defining and fascinating aspect of the breed.
