There is quite some speculation about the origin of this breed. Some claim they would be a sub-species of junglefowl before cross breeding with other breeds. Others believe they are a cross-breed of Gallus varius, Green junglefowl or even pheasantlike cross-breeds. How ever, they were created on Sumatra (Indonesia-Sunda Islands) and are one of the oldest fowl breeds. Despite their elegant appearance they are realy game fowl. Under the name Ayam Sumatra they were used purely in the gamepit.
Around 1850 they were imported into America where they gained popularity rapidly thanks to their exotic character. After the gamepit lost interest in this breed the were breed for shows only. In 1883 the breed was given a standard and was admitted in the ASP (American Standard of Perfection) Around this same period they were introduced in Germany and around 1900 into England. After that other European countries followed. The bantam was created in the Netherlands both in black and blue.
Sumatras are an exceedingly rare and largely undomesticated breed of chicken thought to be closely related to the jungle fowl of the far east. They're kept for their beauty alone, for they're ungifted in the egg-laying department and aren't hefty enough to be a good meat bird. As you'll note, their gorgeous, lustrous feathers are their most striking quality, but in addition they're the only breed of chicken whose roosters have multiple spurs, black skin and even black bones!
All of this is true i believe because of my personal experience.
