RIR help sexeing pls

[Kgreenland]

Hi All,

These are my very first chicks, they are 8 weeks old.

I think one is clearly a cockrel and one a pullet the last is a mystery to me, any help would be greatly appreciated.
Thanks!

I only see one cockerel.
The rest are pullets.

Great thanks for your input, the darker pullet in my last picture has feathered slower, is smaller and is darker than my other pullet so I wasn't sure what it was.

Only one male and all the others are females

I have 2 rir pullets right now. One is bigger and darker than the other. Same age. Makes them easier to tell apart. Named them Red and Ruby
