I’m pretty sure he is an old English bantam
No, because Old English Game Bantams have a single comb and no muff/beard (feathers under and beside the beak).
Your chick has pea comb, and a beard. Not a big beard, but definitely present. It's part of why he does not have obvious wattles.
The only common kind of bantam in the USA that has both a beard and a pea comb is an Easter Egger bantam. (Ameraucana bantam would too, but is not common, and probably is not that color.)
His color Is pretty but is rather unusual, thats why I had such a hard time trying to figure out what he was lol.
