Are my 3 1/2 week Quails Male or Female?

1,2,4 and 10 are your boys 3,5,6,7,8 and 9 are your girls

I agree with this comment, although the fourth picture is a bit difficult to tell. The speckled breasts are certainly hens and the russet colored breasts are roos. As others indicated, the white will have to be vent sexed or wait until it either crows or lays an egg. Coturnix will start laying as early as 6 weeks old. Enjoy your new birds.

FYI, this thread is 11 years old, so those birds are long gone.

Wow, I missed that. Got roped in by the recent reply. Hopefully OP is still enjoying the birds though.
