Coco, one of my female button/king quail, was previously kept in an outdoor rabbit hutch before I got her, with only some extra hay as insulation during winter and she did fine. If you have a small group, such as a male and 2-3 females, they will huddle together for warmth and keep one-another warm. Just make sure that if you have multiple males, they have enough room to escape and places to hide for when fights break out.
They may look small, but they are vicious little things with very sharp beaks, and know how to use them, even pecking at the eyes and pulling at the eyelids.
