You do need to find a vet that knows birds. I wouldn't take a quail to a general vet, but there are vets that specialize in different animals. My cats go to a practice that sees nothing but cats. My chinchillas go to a vet that specializes in pocket pets and other small animals. Finding one that knows birds may be a challenge, but it can be done.
Even the specialists here e.g. for chicken and other poultry for farmer often do not know quails.
And they are already rare.
