Noticeable size difference

SO now they are 6weeks old and I'm now wondering if one might be a Rooster!

They both look like pullets.

I say pullets. Btw the size difference as you've been told could be because you got a runt.
I happen to have a runty speckled sussex hen. She's lovely, not much bigger than a 16 oz cup and lays eggs about the size of ping pong balls.

Thank You! I feel much better
The color difference thre me of too. The smaller one has a lot more white speckles!
