Two buff Brahmas. Pullets or cockerels?

[backyardigans]

I have two buff Brahma bantams that are now almost 6 weeks old. I can't figure out what their gender is. They are both rather large compared to my other bantam chicks and behave very similarly. One, however, likes to try to rip off my skin and the other one is more friendly.

So what gender? Any help is appreciated.

Here are both of them:

First Brahma

Second Brahma

Thanks. I'm bummed. We live in the city and can't have roosters, so I'll have try to find new homes for them...
