I never saw what type of quail you are talking about? If it is Button quail they should be in pairs and if courtnex 1 males to 2-3 females. so the trouble is too many males to females and they have injured the female by overbreeding her. Glad to hear you are separating them. Try 2 single pairs in separate cages and the lone male. Although he will not be happy. and like I say it depends on type of quail. good luck.
