Silkie Chicks....boys or girls??

[kfisher123]

I KNOW silkies are really hard to sex but I'm hoping somone can give me some ideas about 4 of our 8 week olds.
Thanks for any help!

I want to say 2 and 4 are roos, 3 hen and 1 I can't see very well so no guess there. But they are harder to sex and these R just my guess.

Give them several more months and then ask again; or else spring for a dna test
