Hey IHAVECHICKENS2, if that is a bantam sized rooster it might be a blue wheaton oegb. i have one myself very nice and gentle yet very cocky toward the rest of the flock.
Thanks and I have silkies and cochin bantams and he's is a little bit bigger than them but smaller than me buff orpingtons so not really sure on bantam or not. And that sounds like him, but he is aggressive.
