Silkie gender

[Chancy]

These are all the same bird, just wondering if he is a rooster?

How old is the bird? If it's entirely grown up, then it's probably a hen. If it's partly grown, then I don't know. (I don't really know much about silkies, but I'm sure adult roosters have more comb and wattles than that--which leaves the question of what age they get them!)
