Help identifying sex!

[mathischick3]

We have 5.5 week old chicks we got from Tractor Supply. Calling all chicken experts to help identify sex. First pic is Noodle. It is a Buff Orpington, and I am certain he is a rooster. Please prove me wrong. Ha! 2nd and 3rd are both Barred Rock and I am uncertain. I think pullets, but I may be wrong.

Noodle does look to be a cockerel based on his larger red comb and wattles especially the reddening before 6 weeks. oreo and napoleon are both pullets! BR pullets are much darker compared to BR roos. Congrats!
