I could be wrong. Wouldn't be the first silkie to fool me. Some are really hard to tell from photos especially.Your silkie just looks like a roo. The boys usually get taller, lankier looking. Something about the tail just looks more like a boy. He still looks young and has a lot more filling out to go. Looks like a nice silkie boy, (or girl, if I'm wrong). The girls usually are shorter, rounder looking. You will know for sure if he gets the long streamer feathers coming off the back of his head. Either way, it still looks like you have a nice bird.
