Roosters or Hens? Please help!

[ailron]

These guys, or gals, are 10 weeks old and I need to know if they are roosters or hens. I think they are roosters judging by the combs and waddles (wattles?). What do you think?

Do you know what breed they are?

 

[ailron]

They were supposed to be pure RIR and pure Buff Orpingtons. It appears very few of them are pure and most are a mix of the two breeds or possibly more.

Oh boy...looks like quite a few roos to me. I see 4 or so right off the bat...Is there any way you could post 1 pic for each bird?

Unsure on gender - I'm the world's worst guesser. Good looking birds, though.

I thought they were roosters but wanted more opinions. I probably have 40 that look like this. I want to make sure I sell the right one's and just keep my hens. Thanks a lot for your help!
