Here is my tip on Coturnix- They are the most valuable commodity out there in the quail world. All varieties (not breeds) are just colors and look the same when butchered. Coturnix have many uses- pets, eggs, meat, and their eggs go further in egg art. I would avoid learning from the internet as there is a lot of false info out there. Sit down, do some research, get journal articles, that's how you will learn about this great bird.
