Do you have central air/ heat ducts? if yes, they are not separated far enough. Separate buildings, separate ventilation, as in @rosemarythyme 's article.
You can have some tests run on live birds; check your state veterinary path, lab.
Personally we never bring in outside birds, except Marek's vaccinated chicks from tested hatcheries, trying to avoid disaster.
