Are we boys or girls?

[chickenlisa]

I have 7 chicks who are almost 2 weeks old- they hatched here and are mixes of Olive Eggers and Black Copper Marans...the one with the red zip tie may be full BCM.
Can you give me your best guesses if you can who is a boy and who is a girl? I'd appreciate it so much! If more pics are necessary, I have them...just ask. Thx.
#1 Black OE


#2 Blue OE


#3 Black OE


#4 Black BCM or OE


#5 Blue NN X OE Little Puff


#6 on left and #7 on right Blue OEs

Number five appears to be a roo judging by his wings. As they get older it will be easier to tell. I think the rest might be pullets.

Thanks!!! I hope you are right about there only being 1 roo...I do not want any more Roos, so they'll be re-homed or culled...I don't have the heart to cull them yet...so I hope they start to show who they are sooner rather than later...
Anyone else care to offer your opinion? I'm not seeing any posturing yet, and have seen little chicks stand tall like Big Guys even at a week or two old. Some of their legs look thicker than some of the others now...So I wonder if those will be roos.
