New to Silkies (and a mix of something????)

[Friskybinx]

New Silkie mom here and I'm curious if any of mine are showing any signs of hen vs roo. They will be 3 months old here shortly. I know these guys are very difficult to tell but not sure if sometimes you get lucky and can tell early.

Also, any guesses on what the heck my mix is? I'm utterly obsessed with the coloring and how it looks like a tiny hawk.

They all look to be pullets to me. Small, flat combs on all of them. The mix could be anything. Looks pretty much like a Satin Silkie to me.
