Amrock Bantam
American Rock
The Amrock is the American version of the Barred Plymouth Rock, a classic dual-purpose breed known for its striking black-and-white barred plumage. Valued for its gentle temperament and reliable production of brown eggs, the Amrock Bantam is a hardy and friendly choice for any backyard flock.
Characteristics
The Amrock Bantam is a sturdy, well-built bird with a distinct body shape often described as resembling a lying church bell: broad at the rear and well-rounded. It's a utility-focused bird with a powerful but graceful appearance.
- Weight: Roosters typically weigh 2.6 - 2.9 lbs (1200-1300g), while hens are slightly lighter at 2.2 - 2.4 lbs (1000-1100g).
- Body Shape: They have an exceptionally broad back and rear, with a backline that runs straight to the saddle before sweeping into a full tail.
- Head: The head is somewhat coarse with a bright red single comb, red earlobes, and large, lively reddish-brown eyes.
- Legs: The sturdy, clean legs and feet are a bright yellow color, giving the bird a medium-high stance.
- Temperament: Amrocks are famously calm, friendly, and docile. They are easy to handle and make excellent pets for families and first-time chicken keepers.
Egg Laying
Originally bred for both meat and eggs, the Amrock Bantam retains excellent laying capabilities. They are reliable producers of light brown eggs and are known to lay well through the winter months.
- Egg Production: Hens lay around 180 eggs annually.
- Egg Size & Color: The eggs are a good size for a bantam, weighing approximately 1.4 oz (40g), and are light brown in color.
- Broodiness: Amrock hens are known to go broody and are generally considered to be attentive and capable mothers.
Hen vs Rooster
The most significant difference between the rooster and hen is in their barred patterning. The rooster has equally wide black and white bars, giving him an overall lighter, grayish appearance. He also develops a larger, upright single comb and long, flowing sickle feathers in his tail.
The hen, by contrast, has black bars that are twice as wide as the white bars. This makes her appear significantly darker than the rooster. Her comb is smaller and less prominent, and her tail is shorter and lacks the rooster's decorative sickle feathers.
Climate and Housing
The Amrock is an exceptionally hardy breed, well-suited for a variety of climates but particularly renowned for its cold tolerance. Their dense, fluffy plumage provides excellent insulation during harsh winters. Their single comb can be susceptible to frostbite in extreme cold, so precautions like a well-ventilated, dry coop are important.
They are adaptable birds that do well in both confinement and free-range systems. Their calm nature makes them easy to manage in a backyard setting, and they are excellent foragers when given the space to roam.
Color Varieties
Barred Patterning
The Amrock is recognized in only one color variety: Barred. This pattern consists of distinct, parallel bars of black and white across every feather. The visual effect is a classic 'cuckoo' look that is crisp and well-defined. The barring continues down to the skin.
Autosexing Chicks
A notable feature of the Amrock is that it is an autosexing breed. This means the sex of day-old chicks can be determined by their appearance. Male chicks have a large, diffuse, light-colored spot on their heads and are generally lighter in color. Female chicks have a smaller, more defined head spot and are darker overall.
History of the Amrock Bantam
The Amrock's history is tied to the American Plymouth Rock, one of the oldest and most popular breeds in the United States. The large fowl was developed in Worcester, Massachusetts, from crosses of Cochin, Dominique, and Java chickens and was first exhibited as the 'Barred Rock' in 1869.
The name 'Amrock' is a portmanteau of 'American Rock' and is primarily used in Europe, particularly Germany, where the breed was imported in 1948 as a utility fowl. While the American standard focuses on the Plymouth Rock for exhibition, the Amrock line in Europe was often bred with a greater emphasis on vitality and production. The bantam version was developed in both England and Germany to create a smaller, more manageable version of this classic and productive breed.
