Is this white chicken bantam?

I bought 3 bantam chicks a month ago, I have my doubts the white one is bantam, she’s a lot bigger than the other two. Also any guess on genders? They’re about 10 weeks

Buff is a male. Need better pics of the blac. White looks female, but I'm not certain.

Do you think the white is bantam or standard sized? She’s a lot bigger than the other two, all barnyard mixes though so I’m not sure how much height can vary

Not sure. Likely standard.
