That's what I had to do with the first two sets. Same feed, but the second try yielded better results, I think due to better hatching stock.
I used chick starter with ground up mealworms and peanuts. They didn't grow quite as fast as the third batch with game bird feed, but they got to full...
I think you may have had subpar hatching eggs. If they make it through to adulthood though, their offspring may be fine. Or, maybe something in the hatching. My first set (coturnix though) were less than perfect, but their offspring are fine.
