It's too young to know. I think it looks like a splash silkie, but it's tough to tell. Our silkie roo crowed at around 3 months, which is fairly early. He also started doing the "dance" around a week before the first crow. Watch for these sighns, and you should be able to figure it out at about 2-4 monthes IF IT'S A ROO: Very large, brain-like comb, up-right posture, keeping watch alot, a bit fiesty, more rough feeling feathers, crowing, and sometimes very sneaky (our rooster would slip through the fence of his enclosure), and also roo's (strangely) are smaller them the girls.
Hope this helped, and good luck!
