Light Brahma 4-5 weeks old - Hen or Roo?

[CluckNRoll]

I have 4 pullets (supposedly) from TSC that are around 4-5 weeks old, I think closer to 5, but I can’t be sure. The biggest, my light Brahma, has gotten pretty bold and jumps/pecks at me any time I put my hand in to change their food/water and clean out their brooder. I’m starting to wonder if she is really a he? I know this breed is tougher to sex until later one but I was hoping someone with more experience (this is my first year having chickens) could help me. We didn’t want any roosters so I’m hoping it’s not.

So far looks like a pullet.

I agree, looks like a pullet. I know people say Brahmas are hard to sex, but my light Brahma cockerel was obvious at four weeks
