10 Week Old Olive Egger- Boy or Girl?

[nightwing1]

I purchased an Olive Egger and a Sapphire Oliver Egger from a feed store (I think they get their chicks from Cackle Hatchery) 10 weeks ago as day-old chicks. My gut says that the Sapphire Olive Egger is a girl, albeit a little darker than I thought she'd be (I know, lots of variables), but I'm questioning her buddy (Sonic). Sonic has a strong personality and wants to be wherever the other chick (Shadow) is (legit scaled my leg up to my shoulder while I was holding Shadow), although she/he spends more time snuggling in my lap and falling asleep than any other chick I've had regardless of where her/his buddy is (even as a 10 week old). Her/his comb normally is as pale pink as the other chick, unless there's a stressor or activity, and then it gets a little redder (she/he had just jumped up on my shoulder in the picture where there's a little more redness).

Am I overthinking this?

I think both are pullets. The blue one has the larger comb but it is pale, and her color looks even like a female.
