How to tell the gender of Coturnix Quail?

[TheBirdLady2001]

Hello! I need help ASAP! I need to register my quail, and I was only going to register the adults, but I now have 8 one week old chicks. Is there anyway to tell the sex? I know for the brown and golden coturnix you can tell by the feathers on their breast, but I also have two white ones. How do I tell?

Other than the wild and gold colours you can't sex them visually. You will have to vent sex them when they are old enough or wait until the boys start crowing.
