Any guesses on my chicks yet? Pullets or Cockerels?

I am new to chickens and I know at 3 weeks they are hard to tell, but I was wondering if anyone could tell if they are going to be pullets or cockerels yet?

Did you get them as a straight run? I'm getting a lot of roo vibes, but they're actually just too young to tell right now

They are supposed to be all girls, but between 24 of them I am bound to have a boy or two somewhere, I also got a mystery "rare" breed chick, which I am starting to guess is an additional Easter Egger, because I only ordered 4 of them, and the mystery chick is a straight run hatchery choice.

Did they end up being barred rocks or cuckoo Marans?
