Name that breed!!!

This guy showed up on his lonesome. Tried to hang with my neighbors chickens then my neighbor with no chickens, then in some bushes and trees near my coop and finally invited himself over the fence! My roosters have only engaged him only when he gets to friendly with the hens! He’s stunning! Those black tail feathers have a deep violet sheen! I guess he’s a barnyard mix but I’d love to hear what Y’all think!
