We use quail eggs just like chicken eggs. I make delicious cheese omeletes using olive oil. My wife uses them in meat loaf and other dishes requiring eggs.
I always break them in a bowl first since I always get eggs shells in them. I like to get those shells out since I don't like the crunch!
We boil them for salads and dyed them for Easter. And many of my friends will take all I will give them. I don't notice a difference in taste between chicken and quail eggs myself. Any egg that does not come from the supermarket is superior in taste as far as I am concerned.
I figure making meals of the eggs pays for all of the feed, etc. And, then, of course, are the quail themselves. Delicious.
