2 week old Dark Brahmas - same age, very different size?

[casualchook]

Hi everyone, first post here! I have some questions about two Brahma chicks.

I have acquired my first brooder chicks - two Dark Brahmas. One is considerably smaller than the other.

I was told they were both pullets, 2 weeks old and it is definitely too early to tell, but I wanted to post here to get any opinions. I plan on still keeping the roo out of the two.

The large chick is Banana and here is Pyjama:

Any tips are appreciated!

Thanks

The larger one could be a rooster. Is there any chance the smaller one could be a bantam Brahma?

I would also add that it can be a runt, I have one australorp chick runt that grows slower than others.

Update on the two chicks, now 6 weeks old. I'm about 95% sure Pyjama is a roo due to the feather colouring but I'm stumped on Banana.

Banana is massive compared to Pyjama, incredibly docile and lets me hold as much as I want. Pyjama is flighty and hates being held. Holding out hope that we have one roo and one hen because I'd love to keep both.
