What gender are these little ones?

[Frosty_2503]

I’ve got 15 chicks, black copper Marans and olive/Easter eggers. Some of them are pretty obvious who’s who’ve but the others are more difficult. Help! The marans are 5 weeks and the eggers are 6.

I think Dixie, Velvet, and Olive are boys, and all the marans except for number 4 are boys.
