Don Schmidt lives on a chicken farm in Horse Island, Louisiana. He is unpopular at school as well as at home. He has absolutely no friends and everyone refers to him as "new kid," even though he has lived on Horse Island since kindergarten. At home his mother constantly refers to his dead sister Dawn, and thinks the world revolves around herself. Out of loneliness he befriends the chickens living in his backyard and they become his best friends. Don's luck soon changes when he becomes the youngest person ever to win the chicken-judging contest at the local dairy fair. Everyone wants to be his friend and his mother seems to care about him a little more, but not enough to stop ordering him around. Don is content with his life until he finds a metal box with a birth certificate in it. The birth certificate belongs to a boy named Stanley. Don wonders who Stanley could be and decides to ask his father. His father simply tells Stanley that it is his birth certificate and they changed his name to Don, because the uncle whom he was named after was a bad man. Don doesn't believe his father and begins to believe that Stanley is actually his twin that got kidnapped when they were younger. Stanley isn't real, but Don believes he is and talks to him like he was a normal person. Don soon learns that the hidden birth certificate isn't the only secret his parents have been keeping from him. Once he learns one secret he is hungry for more, and then they all unravel into a shocking, unforeseeable truth.
