Sumatra chickens are primarily an ornamental breed kept for their attractive
plumage. Most often they are pitch black with a green sheen throughout
the body and tail. The breed additionally comes in blue and white
varieties. Males usually weigh between 4 and 5 pounds, and females weigh
between 31⁄2 and 4 pounds. Hens lay about 100 white eggs a year. Both males and females have no wattles, and males often have multiple spurs.
The breed is considered a primitive one; the Sumatra retains a strong
flying ability, unlike most modern chicken breeds.
A unique feature of the Sumatra is that males have multiple spurs, with Sumatra sometimes having as many as 3 spurs per leg
