Gender at 3 weeks?

[yakitori]

I’ve read that some coturnix can be sexed at 3 weeks... so I was wondering whether you seasoned quail keepers out there can tell what some of mine are!

If you can also kindly let me know what their official colorations are, I would be deeply grateful <3

Apologies for the incandescent lighting, I can try to take better photos if neccessary...


Wild #1



Wild #2



Wild Blue


Wild Brown/red?




Gray back




Dirty white (used to be silver down, lol)



And last but not least, my little wry neck baby...

The first 2 are boys, the rest are not feather sexable varieties. Lovely birds.

I agree. First two are boys, the rest not feather sexable.
