Silkie: Hen vs Roo? Help Please! :)

[Leesa Blank]

Hi Everyone, could I get some opinions on my 3 silkies and if you then they are a hen or a roo? I have 2 black and 1 white. The photos are numbered, thanks so much!! I'm sorry the photos are out of order

BIG guess on my part . 3 looks roo, the rest pullets.

Really need to see these birds facing forward, with crests held or tied back to show full extent of comb. How old are they? Age is very important and doubly so for Silkies.
