About a week ago, both my budgies Pete and Luna started sneezing uncontrollably for about 30 seconds or a minute, then stopped. I decided to just keep a close eye on it, but they often have a sneezing fit almost once a day. I’ve been watching them like a hawk, and yesterday I noticed they were tail bobbing while they were breathing, which I believe means something could be wrong with their respiratory systems..? Anyways, other than sneezing and that one time I saw them tail bobbing while breathing, they have been eating fine and singing and playing normally. They are right underneath the air conditioning unit, it never seemed to bother them before, should I moved their cage or should I have them checked out by a veterinarian? Thanks.
