I have separated the males from females (actually I have one male in with the females and three males in another cage). What should I look for in deciding which male to keep and mate with the female for future hatches? I realize any visual preferences like size, feather color, lack of deformities and general health come into play. What do you look for in your quails to help you make a final decision in who stays and who goes? Also, do you tend to keep other males around in case anything happens to your main roo?
