My Quail still are not laying. What am I doing wrong?

[Buffalo Mountain Legacy]

Last fall (end of October) I hatched 6 northern bobwhite quail in the incubator. Out of those six, 5 have made it to today. 4 females and 1 male. So here we are 7 months later and I still don't have any eggs. They are on a 22% crumble feed with worms and seed mix. They also have oyster shell available to them. They are in an outdoor predator proof 15 x 12 aviary with coop, grass and all the works. They get plenty of sunlight. What do I need to do differently? What am I doing wrong?

I don't raise quail, but...
