Possibly a male, based on that reddish coloration and the redness of the face. If you see any long, pointy feathers developing around the shoulders or the base of the tail, it's a roo. (If people agree or disagree on points, please let me know. I'm trying to get better at sexing birds!)
How old? Is that coloring on the wings reddish or brown? In many breeds, copper coloring on the wings is a male trait. I don't see any pointy saddle or hackle feathers, though.
