HELP-Silky Sexing!!

[sillyovrsilkies]

Okay...this is my first time raising chickens/Silkies, so I need a bit of help determining sex:

I belive this is a pullet & 3 roos...The silky in front on right is definitely a roo b/c he's the only one I've observed crowing...the other 2 have a large wattle...roos?

Roo?

Roo Too?

Is a large wattle a dead give away for a roo? The one I've heard crow has a small crest & small wattle, so if I hadn't actually seen him crow, I'd would've guessed roo.
Any other pointers for sexing silkies would be greatly appreciated!!

I cant say for sure, but they both look like boys, and they are very pretty.

I believe the first one is a roo, but I'm not sure about the second one.

In the reposted pic with 4 birds, you have 2 roosters and 2 hens.
