It is a hatchery stock silkie. Hatcheries are not concerned with meeting the breed standard, more with output of fertile eggs. As a result, hatchery stock generally don't look quite like all those oh so nice looking breed specimens online & some like your bird can have several 'faults' like no crest(pouf) and also having a single comb- supposed to have walnut comb.
The comb is way big at this age, very likely a boy.
