Need help sexing this bugger

[Pontata]

Hi, I have 4 quails, 2 males, 1 female, and I don't know what the heck this is.

Can anyone help me with the gender? Couldn't tell which by vent sexing. This is all the same quail.

Looks like a female.

For coturnix quails, males would have a more 'rust coloured' breast, where as females just have spots.
Here's a picture I found off google images of a male coturnix quail:

You can see the orange on his chest. ^-^
