Boiled/fried/scrambled/pickled coturnx eggs are all good!
The only problem you will have is in complicated baked goods, where you need complicated measurements, like 3 yolks to 5 whites and sutch.
Other than that....Coturnix eggs are gosh darn fine eating!
My main reason for raising them was for Chicken Egg replacement, and they have done that and become much more!
