Barred rock questions (multiple pictures)

[Rippley88]

Hello, new here, and newish to chickens, family had some 20ish years ago. So January 31st we picked up 15 barred rock pullets, and my wife was hoping to get a rooster out of the group, because occasionally some will slip through, I'm not sure, thinking they are all pullets, which means I would need to source one if needed, but can't tell myself. I'll post pictures and any help would be appreciated.
Thank you in advance

I see no cockerels.

Boy Rocks are really easy to distinguish from the girls.
Their barring is "reverse" of the girls.
Once you see it, you will know it.
Girls are dark background with light markings.
Boys are light background with dark markings.
That is the easiest way for me to describe the difference.
Boys are just lighter in appearance.

I cannot find a better photo right now, but this one does show the difference in how much lighter cockerels are compared to pullets.

Thank you all for confirming the suspicions, guess I'll need to try to find a Cockerel
