Are these pullets or cockerels? Marans and Cochins

[RuffIedFeathers]

All birds are 10 weeks old.

Pic 1 - Black Copper Marans
Pics 2 and 3 - darker partridge cochin
Pic 4 - darker partridge cochin
Pic 5 - Lighter partridge cochin

I feel like I should be able to tell by now, but I don't have experience with these breeds. I think they're all cockerels, except the lighter cochin. Please tell me what your guesses are. Thank you!
