Feather sexing help

[ChicksinPR]

I have these young quail that are 3+ weeks old right now . I am hoping they are girls because they aren't showing the solid rust colors.
1st 2 pictures are the same bird.

3-5 pictures are the same bird. Different light/pose

Thank you in advance.

I am just unsure of being male because of the spots and color not being texbook

All look like girls! Occasionally you'll have a late bloomer boy but looks like girls for now

The first three pictures don't show the chest clearly enough. The last two look like hens.
