7 week old olive eggers with no red in comb/wattles... are we pullets?

[MySuburbanLife]

We let our broody EE hatch some eggs we got from a breeder-- they are BCM roo over EE hen. I'm really hoping all three are girls and anxious to know for sure!

Chick 1 was fast to feather out, has a light (yellow/flesh colored) pea comb and nearly solid black body.
Chick 2 was fast to feather out, has a dark (blue-black) single comb and solid black head/neck with variegated black/gray body.
Chick 3 was slow to feather out, has a dark (blue-black) single comb and solid black head/neck with lighter variegated black/gray body.

At 7 weeks with no redness in comb/wattles, can I hold on to the hope of all three being pullets? Does speed of feathering out and the lightness of their body feathers give any clues about their sex?

Pictures would make them a lot easier to sex. It is hard to sex just off of description.I usually sex by feather color/pattern and comb.

Here are pictures of the three OEs in question:

I'm seeing pullets, but the second to last might be a cockerel.

I just went out to feed the chicks and picked up the second to last chick and noticed some coppery feathers coming in on its neck (which you can see in the picture) and on the shoulders. More evidence of a cockerel?

I find with EE's if they get red on the shoulders will mostly become a roo. If the chick starts getting red on the breast area it will mostly turn out to be a pullet, but I am pretty sure that this does not apply to BCMs and only EEs. If the chick in question doesn't have any red or bright pink comb or wattles by now she is probably a pullet. I also found this thread very helpful with sexting EEs and just general tips for sexting chicks https://www.backyardchickens.com/t/463817/easter-egger-sexing-tips-and-tricks-pictures-included

They all look like pullets to me.
