Gender please? Video included

[TonysChickens]

Can you guys check these two birds out and tell me if they are cockerels or pullets?
The barred rock, and one of the EE in the video. They both have larger and redder combs than the others. I have 2 EE, and one has a redder larger comb than the other.
All of them in this video are 7 weeks old now.

I'm fairly sure the barred rock is a pullet.

The Barred rock is a pullet. If it were a roo, it would have a lot more white barring. The others look like pullets too but not sure.

I thought the barred rock was a pullet early on because of the barring, but the comb today just looked so much bigger and redder than all the others so I started having doubts. Also noticed the EE's comb is bigger than the other also.

Barred rock is definately a pullet. If it were a roo: it would be lighter in color, comb would be bigger, and wattles would be showing. I got 4 barred rock roos that are 5 weeks old and they all have those traits. My 4 pullets, 5 weeks old, look like your pullet.
