help sexing 3 week old chicks

These are mutts that hatched 3 weeks ago. I think there are 3 pullets and one cockerel. My fiancé thinks we have 2 cockerels. Would like your opinion please! First off is a Banty, who may have some OEGB in it. I'm thinking pullet fiancé thinks cockerel.

Third was my favorite, I'm very sad but he is clearly a cockerel.

Lastly is number 4. This one had spraddle leg and needed hobbles. it is doing much much better but growing at a much slower rate than the others.

They're still a little young to tell, however, the little gray (blue) one right now looks like it might have a good chance of being a roo (judging by the comb size / color).
