Help with sexing 7 week old easter eggers!

[Engelvis]

Hi all, I have half a dozen of 7 week old easter eggers that we got from a local breeder. aren't allowed to keep roosters where we live, so I am hoping we only have pullets. Now that they are a bit older, I'm hoping their gender will be distinguishable.

Other threads have told me to look at colouring, but they only spoke about brown chickens and mine are black and yellow. I would appreciate some help with identification!

Chicken 1

Chicken 2

Chicken 3

Chicken 4

Chicken 5

Chicken 6

I'd say 2 is a cockerel.

2 and 3 are cockerels

Yup, I have raised many EEs and the first black one with the dark comb is definitely a boy; his comb and upturned tail are the two giveaways.
The second white one could go either way.
