They look like pullets to me, at 15 weeks of age my Barred Rock cockrels have a great deal more comb and are starting to grow wattles. Those girls in your picture don't display any of those signs. I'd say they are most definately pullets. At about eight weeks the cockrels can be told from the pullets just by the comb development alone, with most chickens.
