(2) Placement of a youth by the youth authority in a youth care center does not terminate the juvenile court’s wardship over the youth or the custody of the youth authority. The center may retain such youths in full- or part-time residential care or, with the consent of the youth authority, may place them on a full- or part-time basis in foster homes.
