We need a lot more info than this to be able to help.
Maybe you can start with these questions, which are from the emergency section. This way, people here might be able to help more. Also, what other types of poultry do you have, where are they housed in relation to the quail, etc. Are they inside or outside? Have you gotten any new birds lately or visited any places where there are poultry? Have you been anywhere that you might have brought disease in on your shoes? Describe your biosecurity practices, etc.
