Can anyone help? Are these roosters?

How old are they? I would guess the one in the front is a male and the one in the back is a female.
One in front is definitely male, and I suspicion the one in back as well...that comb is pretty reddish pink as well.
Black/white is most predominately a male EE color...and I don't think the bird in the back has enough patterning to be female...but it could...I would wait a bit more on the one in the back before calling definitely.
