7 week old japanese bantam gender

[FattyChickens]

I've asked three times now, I really wanna believe that it's a pullet so that I don't have to rehome her.
Her sister's comb is much smaller though and I'm worried lol.
Comb doesn't look red to me but it definitely has a little color in there. Can pullets grow their combs at different rates?
Also how big are they supposed to get as japanese bantams? They're both like, a handful lol

Can you get side, by side pictures of those two?
I'm thinking cockerel... I may be wrong though.
