Not all Silkies are born with big puffs on their heads, but I do see a little bit of a crest there. I can't see it's feet very well but they appear to be feathered and dark. Silkies also come in all sorts of colors and many do look like this when they hatch. I would say that it probably is a Silkie. You should be able to tell in a few days though when the feathers on the wings start coming in. :) Keep us posted!
Thanks! I will!
