Ultimtely It Depends On The Egg Sizes.... To Single Stack As To Allow A Hatch Within... I Would Say It Should Easily Accomodate 60-70 Eggs At Once. They Will Dry Quickly In There And Since Quail Are Born With On Board 4 Wheel Drive Dont Worry About It Looking Crowded, No Longer Then They Would Be In There After Hatching They Will Do Just Fine
