Many of us have poultry and gamebirds and on the same property nonetheless. Practicing good biosecurity is a start. You can have a pen near chicken pens, just not having a chicken in the pen with the quail and sharing the feed/water, cuddling with the quail, etc. What I do, is first feed the quail and care for them, close up and then go to the chickens, ducks, and all those critters. Microorganisms are in the air and things can transmit among your clothes, but it is safer to do the quail first and then chicken. The pen, as long as sanitized and no chicken prior in it, should be fine for the quail until you make room for them elsewhere.
