Feather Sexable Coturnix Crosses?

[emnic94]

I have 4 quail currently, a Jumbo Brown male, two Jumbo White Wing females, and a Manchurian female. I know Manchurians are feather sexable, and my understanding is that the White Wings are a cross between Brown and White, and as long as there isn't so much white that you can't see the differences in them, they are still feather sexable (This was the case when we hatched them last year). My question is, if we hatch eggs from them this year would a Jumbo Brown/Manchurian cross be feather sexable? I'm fairly new to quail, so I am not as familiar with their color genetics Pic of our babies from last year for attention.

They should be, but you might get some surprise mutations in there.

Thanks for the response! I'm hatching for someone else who wants us to keep them until we can separate them into male and female, so I was mostly just curious.
