Where did he come from? My first thought is mixed breed, so if he's from a hatchery he's likely an EE. A closer pic would help, I can't really see what type of comb he has.
EE is Easter Egger, sorry. Often sold by hatcheries as Ameraucana or Aracauna, but they're really not those breeds. EE are basically birds bred to lay blue or green eggs----although with roosters, it's kind o fa moot point
