I agree with wheaties but am saying like him the third pic might be a roo. Do see some black send pics with wings closed from side.

They were not real excited to participate, seemed they really didn't need to be distracted from what they were doing.
Anyway, here we go with side shots. I am thinking maybe, number 4 might be a roo. Larger comb, and the only one with any hint of darker feathering at this point. It is also the only one lacking feathered legs.
These are not in the same order as the first round.

Group Shot - Suspect Roo in front and center
It looks to me like #7 also has a slightly bigger comb. I also noticed that some have black spots on their heads and some don't. Is that also an indicator? I suppose not or it would have been mentioned by now.
OK, so we have reached a definate conclusion.
The real issue, wait three weeks, and you can definately tell. There are three fairly obvious traits.
Black bar coming in on wing - Roo
Larger Combs - Roo
Earlier Feathering in on Shoulders - Pullet
3 Roos - 4 Pullets, not a bad start for breeding.
