Can someone tell me what breed my chicks are

I can't guess on breed but I can early guess on gender.
First pic looks to be a male, second looks female but need a better pic of comb to confirm.

A couple more weeks and it'll be more obvious.

Where did you get them from? Do you know what breeds are possible?
