Maran chicks 6 weeks old hen or roo

[Sophie4321]

I have some maran chicks and various other breeds that are 6 weeks old
I have already taken out some obvious roos (bottom pick) but I not sure if there are any left or not
There are copper and weaton marans, 1white legion, 1 black legorn, 1 light sussex, 2 buff orpington, 1 arucuna x lavender orpington, 1 cream legbar hen
1 hybred layer x orpington

I see no other obvious roosters than the two in the bottom picture. Watch them in the next 2 weeks or so for sudden red comb development.
