i think quails deserve as much space possible, they are a great little bird. 1 ft sq is not enough, they use to keep chickens in tiny metal cages, they said that was ok, we all know it's not. so i would say give them as much space as you can, and keep them with sand/dirt boxes they love them and branches to lie under, it makes them feel safe, you will be rewarded with some very happy quails.
