How Do I Increase the chances for a Couturnix Quail to go Broody?

I gave my budgies eggs to sit on, will take them out on hatch day. It's been about a week and so far so good.

my third bobwhite is going broody now. I have one pair in a 8x20x6 aviary made just like their natural habitat. the bobwhite now has a couple more days to go!!!
