When I first got my quail, I had 6 in a 21 square foot area and I had some problems with fighting - I think because I didn't have enough hidey places and one of them was stressed and frightened. I think having wide open spaces could frighten them but if you had hidey places / bushes etc, the larger space would be great for them. Now I've sorted out some more hides for my quail and they have an outdoor area which has long grass, we have peace and they love exploring around.
My outdoor run has a galvanised mesh floor which I covered in soil and now has grass growing - they love being in the tall grass, hunting for bugs, digging in the soil etc. I've recently had to cover the whole lot in 1/2 inch mesh because a cat got its paw through the holes that were there before and got the back of one of my quails (she's ok).
I really think having the bigger space and letting them do some natural behaviours is a wonderful thing - I love watching them and getting to know their individual little personalities and they're happy too
