If you hatched those 9, then the only thing I could suggest is you order more eggs and hatch a few more. Otherwise, it will be a long process for you to incubate 5 quail eggs at a time from that one hen to get the covey to the size you want it.
The other thing I would suggest, if you haven't already done so, is to separate her from the males, as they will all court until she is too exhausted and die. And no, I'm not joking.
Edited... OOPS! That line should read, "put her in with one male and remove the rest".
I was distracted by a co-worker and didn't proof read before I submitted it.
