Guesses on these silkies?

[amandac]

Hi. I have a good guess on these chicks, but wanted some second oppinions from any silkie experts. I know they are hard to sex, and I am not even sure of the age, I'm guessing 4 months. I appreciate any help!

I am very new at this chicken thing. My guesses are kinda obvious. Thanks for the help!
