I did craigslist to get an initial flock, now I'm planning to hatch my own from here on out. If you're planning to breed yours in the future make sure to save your extra males (probably in a share cage/bin) until you're sure your "best" male is fertile and good with the girls. I made the mistake of keeping only the one, and had to buy eggs all over again when he turned out to be a hen-scalping little monster.
Re the netting: I get it as taut as I can, then check by bopping my hand against it that a quail flushing upwards would stop at the net and not be able to hit with enough force to whack into the ceiling above (aka put the netting a generous few inches from the ceiling). Then it basically acts as a reverse quail trampoline: they hit it and bounce back down. The stretch of the net as they hit defuses the momentum more safely than whacking into something unmoving would.
It will be winter soon and my rooster got less sweet
