Sexing/identifying 5wk quail chick

[raraschicks]

Hello!
I am hoping for some help sexing this 5 week old coturnix chick. It may be too early but I’m hoping to make some coop decisions soon as I’m going out of town. I’m hoping someone with more experience may have some insight. He/she was hatched from mixed coturnix eggs so I don’t know much about it’s coloring. Seems like vent sexing may be my only option but I’m not sure if it’s too early? No foam and doesn’t seem bulbous like a male usually does but is it just too early to tell? Here is the feathering and vent. Any help would be appreciated!
Thank you!

This one is not feather sexable and not yet sexually active. By the time it's sexually active, you will probably already know because you have eggs or crows.

even my 5-week crower doesn't have a bulge yet either. i think we'll have to wait till like 8 weeks
