rooster or hen?

[City chick]

It looks to me like a columbian wyandotte in the first pic. The zebra striped are barred plymouth rocks and the reds are probably rhode island reds or production reds. The darker pink combs at this age are probably roos, while yellowish combs are pullets. Hope this helps

3rd pic, barred birds in center, both cockerels. (can't see the barred one on the right well enough) Red one in bottom picture is a pullet.
