There really aren't any other good options. Quail are social, so you need to keep more than one, but if you have a male, he needs a harem. You could probably get away with only two if they are both male or both female.
I know that you've spent a lot of time with your quail and want to keep...
This is the first stage of overbreeding. One female is not enough for one male. He needs at least three, preferably five or more.
If he continues to overbreed her, he will start to draw blood, eventually scalp her, and possibly kill her.
