Gender issue

[TheQuailHouse2]

I have four coturnix quail and three of them have been crowing. I don’t know if this means they are male but if you know the best way to sex them that would be great.

We need pictures. I personally have no experience with sexing quail, but others will be able to help if you can post pics.
