6 week old Silkie Sexing

[Grandchicks22]

I know it’s early but any guesses on the sex with these comb pictures?!

New to this…
Top 3 male?
First bottom 2 female and last two no clue seems like a single comb?!

1,2, 5 and 7 looks suspicious but its way too early for silkies. The satins with show earlier.
