BYM - pullet or cockerel? When can you tell?

[JRfarmer]

I have 24 barn yard mix chickens, 7 weeks old!
When can I really tell? Should I be looking at combs or feathers?
I have 8 with large red combs that I’m sure are cockerels. (First 2 pics)

Any guesses on these others ?

Obviously first two are cockerels like you said along with 2, 3, 6, and 7. Keep an eye on 1, could go either way but thinking pullet right now

Pullets: 1, 4, 5,
Cockerels: 2, 3, 6, 7
