What genders are these

[Maddistee]

Hi, all of these chickens are 12 weeks old.

I am having difficulty sexting them and being confident as they are a random mix breeds we got as eggs.

There is one photo of each chicken, i have an idea but just looking for confirmation

Thanks

I think chickens 2-4 are female, but since they're mixed breed, I'm not very confident about it.
