How to tell Showgirls from the ShowBOYS??? Anyone got pix?

DD wants Showgirls. I pretty much *fried* our Showgirl eggs in a "freak LG accident." None have hatched. Sooooo... I am giving in and buying some.
How can you tell the boys from the girls? Do you go by Silkie criteria - waddles & a mohawk = boy? Any other way to tell?
If anyone has advice or photos, I would be so grateful.

Okay. Just thought I'd ask. I suppose I'll end up with cockerals...
