You need to sit down with Both parents and explain to your mother that your quail needs a friend. Quails are like chickens and NEED a friend. just like chickens Quails can get depressed living on their own and could eventually die from this. You need to get it in her head that you will take care of this quail. Feed, water, and clean it and that she'll have nothing to do with it. Is your mother reluctant because She's the one taking care of the one you already have?\
Like I said, it takes 2 months to ship. The eggs will die.
