Roos or Pullets with pix (Olive Eggers and Black Copper Marans)

[Spring Chook]

Hi there, I'd be interested to hear your views on these three. I have my own thoughts .... I hatched all three under my broody bantam. One is an Olive Egger, the other 2 are Copper Marans

A - Black Copper Marans ... boy or girl ?

B Blue Copper Marans

B the Blue Copper Marans again

C Olive Egger

what do you think experts?

PS they were born on the 30th May so are roughly 10 weeks old

Posting a shot from the side view (including tail) and of their heads would be helpful. There is a Gender and Breed thread where I have always received great support in identifying gender and breed. You might want to post there...lots of experience.
Good luck
PS
From what I can see I would take a big guess...
A - roo but would like so see more
B - same as A
C - pullet

Thanks Mrs Feathers,

I'm thinking the black one is a roo, but concerned they all might be!

I have some BCMarans and mine have been pretty easy to tell from a fairly young age. The males have a lot bigger comb on them.
I'm no expert, that's for sure... but I would say both of your Marans are pullets, going by their small combs.
I have no idea on the third one.
How's that for muddying the waters?
