Hens or roo’s? 6 Bantam chicks Please help 😊

I'm very new to this,..
Can you tell which one's are roosters and hens? They are now 5 weeks old.
I cannot tell 5 and 6 apart. They look so much alike.
Number 3 is def the biggest of them all!

1, 2 are Cochin Bantam buff
3, 4 are Wyandotte Bantam patrijs
5, 6 are Wyandotte Bantam red / porcelain

My guess is that 2 and 3 are roosters. #3 is only based on size and some red comb development at #2.

The only cockerel looking one so far is 2. But his/her comb isn’t red. I think they need a few more weeks to mature and be sure of their sex.
