This is an odd situation. This is a young cockatiel in a feed store. I am in a position to guide her treatment - to an extent. This bird will not be taken to a vet. No, not even a fecal. Environment: clean cage, fresh food and water, fed cockatiel seed - no other birds in the vicinity showing signs of illness. Symptoms: eyes closed, heavy breathing - though not audible respiratory distress; stool appears normal She's been there for a couple of weeks - this was noticed 2 days ago. I pulled her roommate - who is asymptomatic - and recommended that she be isolated, low light and warm. My intention is to check her tomorrow for symptoms of being egg bound and to try and convince DH that she could stay with us for a bit. (Wish me luck with the latter.) If I do palpate anything, I'll try the bath and any manual assistance possible from me. How can I distinguish between viral and bacterial infection? Would a broad spectrum antibiotic do any harm? Any suggestions would be really appreciated! Thanks!
