My Daddy's got chickens shortly after we purchased our chicks. His are Sebright Bantams in gold and silver. A Bantams is like a mini version of chickens and the Sebright is one of the true bantams. That means there is no standard (large) version of the breed. The breed was developed by Sir John Sebright early in the 1800s and has the distinction of being the only breed of chicken named for an individual.
His chickens are full grown and lay eggs a little smaller than a golf ball.
