What Gender are these 3 month old white leghorns?

[Caleb M]

I have seven 3 month old leghorns and there are two that stand out to be roos more than the others, should I call them roos, wait longer, call them hens? I can't tell whether or not there is a difference in chest feathers and neck feathers yet but their tails are smaller and have a little pointier tail feathers, not including the bigger, redder, comb and waddles.

From the top pic it looks like you have two little fellas - wattle and comb development is more significant that the others.

Any with large combs are cockerels at this age. I believe there are two cockerels from the pictures.

Yup, I see 2 roos and the rest pullets in the photos.
