Unfortunately I went thru the same thing with one of mine, I'm guessing male those look like streamers, mine was a late bloomer and doesn't act like a rooster, no eggs but has started crowing, and is 7 mo old , I had been told by everyone pullet or sure , due to small comb and it is different from other silky who turned out to be cocktails, now I have 2 boys , I posted pictures on this site you may be able to find in May
Well, this helped me with my little silkie that is around 7 months old. She's a pullet as well I think!
But yeah looking at your girls she looks like a pullet.
