Roo or hen?

Getting different feedback on the barred rock. I’m pretty sure the isa browns are all hens. They were 9 weeks in these pics

ISA Brown is a girl for sure. The Barred Rock is a boy.

Are there are two barred rocks - one with a black leg band and one red leg band - but maybe the same bird? I'd say it's a cockerel. My barred rock pullet is 9 weeks also and doesn't have anywhere close to that level of comb development or wattles. Yours also has very yellow legs, whereas most pullets have black/gray striping down the legs.

The brown also looks like a pullet to me.
