I don't have quail, but when I go to feed my ducks they literally are falling all over each other.
This is why I'm guessing they'd get trampled. To death literally.
Feeding the ducks is kind of interesting. They act like its the last piece of food on the planet even when they are well fed.
But there is a way to recover from this and still work it out.
A lot of people on Youtube can rig up quail cages in very small spaces. They also stack them more than other birds or animals because of it. So if you can't put them together, you could in theory still get it to work. You could have the quail in a garage possibly also.
Let us know how it goes.
