Are these roos or hens? Help please!

[4H kids and mom]

Cuckoo Maran about 4.5 weeks old

Lakenvelder about 4.5 weeks old

And can anyone confirm that my Silver Spangled Hamburg is a pullet?

Also, any clue as to the breed or sex of this one? I just can't figure it out! I was thinking its another Lakenvelder?

Thanks~!
