One of the first sheep to be found in the United States is the Gulf Coast. For centuries they have been found in the southern areas of the U.S. The Gulf Coast history is unknown, however they do appear to be descendants of crossbreeds. It is likely that the reason for their survival for all this time is due to natural selection. The Gulf Coast is able to live in a wide variety of conditions. Their face is open and is typically either brown or white in color. These sheep are small sized and have a well-developed structure. They are free of wool on the underline and legs. Fleece of the Gulf Coast is medium-grade and lightweight. They are durable animals that can even live in the humid climates, such as in the southeastern part of the U.S. They are able to naturally fight off internal parasites and can breed during the summer as well.
