Need help sexing 12 Week old Ameraucanas

[PaulaBt]

Hi,

These birds are supposed to be Blue and Brown/Red but I know that Blues are only true usually about 50% of the time. I am looking for some help in determining roos from hens. I would also be interested in knowing what is considered standard for the two colours.
Thanks!

Pic one is a cockerel.
Pic two has a cockerel in the foreground with a pullet behind.
3 is a cockerel
4 I'm leaning cockerel, but I'd revisit in another week after the saddle feathers come in.
5 is a pullet
6 I could go either way with again... revisit this one
7 is a cockerel.

Bird in pic 5 is for sure a pullet. Bird in pic 4 may be as well. The others are cockerels.

I would agree with the exception that @Frazzemrat1 was right on there being a Pullet in the background of the one picture. But that may just be bird 5 again

As for the colors I'd say you have blue, black, splash and what looks like it may be blue wheaten but time will tell (kind of surprised there isn't red coming into the wings already though so it may just be poor breeding causing the leakage).
