Cuckoo for Cuckoo Marans! Gender help please :)

[jamie7100]

So I got 3 cuckoo marans from McMurray. They are supposed to be pullets, but I am getting a little skeptical. I know one is a pullet for sure, but the other two are making me nuts. I am getting annoyed thinking 2/3 of my pullets might be cockerels. I know these pictures aren't great, but what do you think? They are about 5 weeks old in these pics.

# 3 was not interested in being photographed.

The one I'm sure of is the darkest one on the left. What do you think?

On picture one, the dark one is a girl and the light one is a boy. I think the other 2 may be boys too
