Hen or Roo ?

[kosan]

Here's a couple Chicks I am in question about gender? I have a feeling the Australorp (3 Pic's of same bird) and the 1 Wyandotte are the only Roo's out of the 20 chick I have,, The other 2 Australorps haven't got as big or as bright comb and waddle as the one pictured and the Wyandotte pictured doesn't look like the other 4 i have,,,anyways whats the opinions out there?

How old are the birds in these photos?
What leads you to believe the GLW is a cockerel? Is it the comb? I ask as it appears this bird is developing a single comb, where the other birds likely have rose combs (the accepted comb per breed standard) - the difference is not so much gender related, but a matter of genetics with the undesirable single comb popping up in this bird.

At under 10 weeks, yes, the Australorp is a cockerel.

The Aussie is a cockerel, but the glw looks like a pullet to me.
