Pullet or cockerel?

[Babs_Jellymuck]

Sorry the pictures aren’t the best, they’re a wiley bunch! 6 week old cochin bantams. Thanks for your help! Particularly curious about the black one and the partridge- I’m suspecting roos for both but I’m still fairly new at this.

I see three cockerels. Buff in the back of the first photo, the black, and the partridge.

The buff and the black in the first picture and the partridge in the second are very likely cockerels.
