Any guesses on pullet vs cockerel for my babies?

[Chickenlady1998]

I got them all from a local supply store. They’re all 4 weeks.

1: Assorted Bantam bin. Very curious and always come up to me.
2: Barred Rock. Getting friendlier and is curious around me.
3: Easter Egger
4 & 5: Assorted Color Egg Layer bin. Possibly a Cuckoo Maran. Both of these chicks I got from this bin that look like this are much larger than all the rest.
6: Assorted Color Egg Layer bin
7: Assorted Bantam bin. I’m pretty confident this is a roo. It is very confrontational to all the others and likes to double foot kick everyone.
8: Easter Egger
9 & 10: Assorted Bantam bin. Both are very skidding, but 9 is confrontational toward other chicks and has a larger comb than 10.
11: Olive Egger
12: Assorted Bantam. This is the smallest of all the chicks. By quite a bit.

I’d love your input. Thank you in advance! Also, if you can recognize any of the assorted bantams or egg layers I’d love to know the breed!

7 is the only obvious male at this age. Check back in another 4 weeks

Another 8 weeks?

5 is probably a dude too.

Oh whoops, good catch.

Another 4 weeks, when they're 8 weeks old

thank you! He’s kind of a stinker, so I figured with that bright red comb and that he’s a roo!
