Sexing Japanese/Coturnix quail

[ChickenMama6RIR]

So in picture #1 I'm positive it's a girl, and picture #2 I'm almost certain it's a boy (the one directly beside the waterer). So my question is, is #3 a female as well? I know that speckled chest is female and rust colored is male. But what about kinda rust colored with slight speckles like pic #3?

Ps. I just got these quail. I know there is some dried poop stuck on their toes. I'm trying to figure out how to get it off.

It's a little hard to say from the distance, but I think I'm seeing rust in the chest of #3, which would mean male.

So any rust at all means a male?

Not necessarily, but this one looks like it's right around 3 weeks old, and at that age, if there's rust, the chest will turn completely red as it grows older. Some aren't feather sexable.

Ok good to know! Thank you, I really appreciate it. I'll wait until they're all around 6 weeks until I completely sex them. I've heard some do a louder warble, so I guess they are roosters lol
