Sexing 3 week old "Ameraucanas"

[Mikski]

Hello! I'm new here but have seen a lot of helpful posts. I'm a first-time chick owner, and recently got a couple chicks from my local feed store. These two were sold as "Ameraucanas" but I'm assuming they are actually Easter Eggers? They are 2-3 weeks old right now, and I have suspicions that the darker one is a cockerel. He/she is bigger than the other chicks I got at the time, has pretty thick legs, and the comb seems to be developing thicker/bumpier than the white one. I know it's still too early to fully tell, but does anyone have any insight? I've included pics of both birds' combs, plus a pic of the chick in question from the side view (next to my Rhode Island Red). Thanks in advance!

I would say dark ee could be male but id give it a few more weeks because it can stop growing

Definitely Easter Eggers. The dark one could possibly be a male but still too early to be sure.
