About

The Shamo is a Japanese breed developed from fighting fowl brought from Siam (Thailand) in the early Edo period, and its name comes from Siam. It has a powerful breast, an upright neck and short feathers, and many birds show bare red skin at the centre of the breast. Colours include red wheaten, silver wheaten, black, white, speckled and others; the comb is pea or walnut, and the skin and legs are yellow. Hens lay about 100 eggs a year. Its excellent meat has made it widely used in producing local jidori chickens. On 1 August 1941 it was designated a national natural monument, without regional limitation, as a livestock animal unique to Japan, and the large, medium and small Shamo are all covered. It is extremely combative and reacts noisily to sound and light, so males cannot be kept together and changing flock membership triggers fighting; cocks' spurs can also injure people. In Japan chicks and adults are available from fanciers and poultry farms.
