High Quality Content by WIKIPEDIA articles! The Saipan Jungle Fowl is a breed of domestic chicken. The Saipan male can stand 2-3 feet tall, with tight feathering, shorter tail than most birds and as a 2-3 year old becomes very muscular and upright stature. Hens can weigh as much as 8-9lbs and roosters as much as 9-13 lbs. The Saipan is not a true jungle fowl, it was found on the island of Saipan. It is thought to have been brought into The United States of America by returning American servicemen at the end of World War II including B. W. Saylor, who wrote "The Saipan Jungle Fowl" in 1977. Although the birds encountered at that time were both domesticated and wild on Saipan, it is thought that the wild ones were feral and descended from those brought in by the original human inhabitants. An alternative theory is that they were brought in by the Japanese as occurred in other locations such as Taiwan during the Japanese colonial occupation.
