Quail need 28-30% protein till 6 weeks then can drop back to 20%. So if you've been feeding the turkey starter, you should be able to switch them all to a 20% flock raiser.
While not ideal, you can cut the protein in the turkey feed by feeding scratch grains almost half and half. 8 parts scratch to 11 parts of 28% turkey feed will yield 20% crude protein.
