4 weeks old marans

[Zzzzia]

Hi, I have 2 BCM... they look the same, and I am scared I may have 2 roosters.
They will be 4 weeks old tomorrow, they are the biggest of all my other same age different breed chicks,.are super bossy.
No red comb though. One has copper on wings.
Any ideas?

You should be able to tell in the next few weeks if those combs turn red.
