The Serama are characterized by their upright posture, full breast, vertical tail feathers held upright and tight up to the body and vertical wings held down nearly touching the ground.
They are the smallest breed of chicken in the world. Typically under 500g, however, 450 grams, and under 350g are preferable. This breed was developed in the Malaysian state of Kelantan, it is thought, from crossing Japanese bantams and local Malaysian bantams.
The Serama is promoted by a couple organizations in the U.S. One is known as the the American Serama Association and Serama Council of North America.
The American Serama as put forth by the Serama Council of North America has now gained acceptance by the American Poultry Association and the American Bantam Association as of April 2011.
Pros: Intelligent, very small & easy to tame. Cons: May need extra care as chicks, good flyers, tiny eggs
