RIR mixes and black australorp sexing help?

[rdilbarova]

I just got seven chicks, ranging from 9 to 12 weeks of age. I need some help determining their gender, since I am very inexperienced with this kind of stuff.


This is Butch, a black australorp who struts around like a rooster, but that may just be because s/he is 12 weeks and way older then the others, and bigger as a result:




This is a chick I have yet to name (in the back), 10 weeks old, RIR mixed with americauna probably:



This is Omelette, 10 weeks old, RIR mix. A bunch of people are saying roo but this one is my favorite so I sure hope not!


In the back of this picture is Monarch, also 10-11 weeks old. No idea what breed this guy/gal is.


The second chick I have yet to name, 10 weeks RIR mix:


This is Cesar, a 10-11 week RIR/americauna mix, probably a roo, but I am just making sure (he is the one with the grey):



And finally in the middle we have Roadrunner, 9 weeks old, in the middle. Unfortunately, I don't have a better picture of him, and I dare you to guess why!:





Thanks for your help everyone!
And if someone sees this that has already sexed Omelette for me, don't be offended, I just really really really don't want him/her to be a roo.

I agree that Cesar looks like a roo. The rest look like pullets to me, omelette may go either way, but considering she is 10 weeks and that lightly colored, probably a little lady.

Really? The second chick down seems like a rooster, but then again, I know next to nothing.
But I am relieved, I thought i had more roos then pullets

Any other opinions?
