He kind of looks like a Silkie/Cochin cross, because he has a ton of feathers on his feet. He has to be crossed with something that has a single comb, because Silkies don’t, and he had to get it from somewhere. So that’s my guess.
He could be a Serama, especially if the other birds were smaller than Silkies. Could the laced birds have been Barnevelders? I think they come in bantam size, and that might fit his coloring better.
