Bobwhites are roughly 23 days, so stop turning at 21 days. I've been leaving mine in a carton, and they are hatching very cleanly. Everything else is the same as it is for chickens. BUT... be patient. I have had an egg pip on day 20, and not hatch until day 23. In my experience, I always see a little tiny pip when they're starting, and they can sit like that for a day. Then the next day you might notice that the pip is just a little bigger. They might hatch then, meh, they might not. They take their sweet time. Just don't panic... don't open the incubator unless you need to add water, and just let them do their own thing. You'll be surprised when you wake up and all the eggs have hatched overnight.
Leave the chicks in the hatcher until they're fuzzed out and dry, and just make sure you have plenty of food sprinkled generously around the brooder floor. After the first day you can place a dish of food in the middle of the sprinkles, and from there on out they will eat out of the dish.
Bobwhites are more skittish than Buttons or Coturnix - you can try to handle them a lot from day one, but eventually they get that teenage mentality where they just don't want to be seen with you.
Let us know how the hatch goes! They're beautiful little babies!
