I've tagged some friends that have helped me through so much and I trust them completely. Since she doesn't seem to be struggling, I believe she's probably OK (not at an immediate risk, but I completely understand and not dismissing your concerns at all). Is she laying normally? Make sure you are not going overboard on treats and at least 90% of their diet is a complete and balanced feed. Keeping dust down and the possibility of mold spores forming will help reduce the risk of aspergillus issues or any other lung issues. She hasn't had any type of trauma before this started has she? Did this start with the seasonal temperature increase?
I'm trying to think of any possible issue.
