4 week old silver laced Wyandottes-- maturing quickly, or all cockerels??

I bought three silver laced Wyandottes that were labeled as pullets. They all three seem to have a comb that is pinking up quicker than our other breeds, with pink wattles too. None of the other chicks that I've seen have wattles yet. Do we think they're all boys?? Too early to tell?
