Can quail servive on chicken layer feed? How much calcium and protein do laying hens need?
Here are a couple of tables (Starter, Breeder) I use when I have my feed custom milled. Yeah, I know, not everyone can have their feed custom milled but this will give you an idea of the nutritional and vitamin/ mineral requirements and what should be in a quality commercial feed.
Only difference between this list and what I feed, is that I feed 24% protien from hatch till death to all my birds, Quail and Pheasants. Feeding high protien feed ( 26 - 30%) for an extended period can cause digestive problems.
This is based on a kcal ME/kg diet for Bobwhite quail.
Crude protien (%) Starter 26 - 30
Breeding 24
Methionine + cystine (%) Starter 1.0
Breeder 0.90
Linoleic acid (%) Starter 1.0
Breeder 1.0
Calcium (%) Starter 0.65
Breeder 2.4
Available Phosphorus (%) Starter 0.45
Breeder 0.7
Sodium (%) Starter 0.15
Breeder 0.15
Chlorine (%) Starter .011
Breeder .011
Iodine (mg) Starter 0.3
Breeder 0.3
Riboflavin (mg) Starter 3.8
Breeder 4.0
Pantothenic acid (mg) Starter 12
Breeder 15
Niacin (mg) Starter 30
Breeder 20
Choline (mg) Starter 1,500
Breeder 1,000
I also have a 'trace mineral' package added to my feed, that list is too long to post here.
A good quality commercial feed should have as a minimal these percentages.

ETA - Methionine + cystine and Lysine have been deleted from commercial feeds in the past 10 years or so, due to cost!
