I noticed my budgies tail was bobbing so i immediately separated him from my others and then monitored him and saw he was sneezing more than normal and sometimes it sounded like he was congested when he breathed. i set up a humidifier for him and ran a hot shower for a bit to help clear out his respiratory system. i dropped him off at the vet today and they called and told me they aren't really seeing any sings of illness, just slight labored breathing but other than that he is eating good and his droppings look normal and the vet tested his droppings and everything came back all clear. From the symptoms i noticed yesterday I'm almost positive he has a respiratory infection and I'm worried the vet is going to send him back to me without doing anything. could he just be hiding his illness from the vet cause he feels threatened? Is there anything i should be asking the vet to do or check for? i have not spoken to the actual vet, just the tech and she said i will be able to pick him up sometime tomorrow. any advice on where to go from here is appreciated
