These birds possess a calm demeanor, yet exhibit a protective nature, making them excellent guardians of the flock. Their distinctive long legs and broad shoulders contribute to their exceptional presence.

History

The Shamo breed originated in Japan, where they were specifically developed for cockfighting and meat production. Believed to have been introduced from Thailand centuries ago, they have since evolved into an admired breed in various parts of Asia. Their popularity spread further due to their aesthetic appeal and resilience.

Care tips

Shamos thrive in spacious environments due to their large size and active disposition.

What keeping Shamo is really like

The Shamo is a Japanese game breed, developed from birds brought to Japan from Southeast Asia. It is tall, upright and heavily muscled, with hard, tight feathers, a small pea or walnut comb and a fierce expression. The Shamo is protected as a Natural Monument in Japan. Several sizes exist, from large O-Shamo to the smaller Chu-Shamo and bantam forms.

A true game bird

Shamo were bred for fighting, and the instinct is strong. Roosters will fight each other, often seriously, and should be kept apart. Hens can be aggressive with other hens too. Many Shamo are calm with their keepers if handled young, but this is not a breed to mix casually into a backyard flock.

Space and housing

They are tall birds and need high coop ceilings and pop doors. Keep roosts at a sensible height to protect their legs. Their tight feathering does not insulate as well as fluffy breeds, so a dry, draft-free coop matters in winter. They handle heat well.

Laying and growth

Hens are poor layers of light brown or tinted eggs. Shamo mature slowly and take a long time to fill out. Hens can go broody.

How they compare

The Malay is another tall game bird with a similar look. The Aseel is shorter and stockier and just as game.

Rarity

Shamo are uncommon in the US and mostly kept by game breeders.

Who they suit

Shamo suit experienced keepers who want a game breed for its history and type and who can house birds separately. They are not a beginner breed or a family flock bird.
