Canary health problem
This requires a bit of a background story so apologies for the length of my message in advance. My parents had a canary home which got attacked by a falcon and lost its wing. I took him to the vet where he stayed for a week to recover and then decided to take him home with me. This was 3-4 months ago.
When I first moved his cage in my flat I kind of realized that he was making weird sounds while sleeping (clicking, wheezing, cough-like sounds). I can’t tell if this got worse with time but it does sound that something is wrong. I took him to a couple of specialists a few times and he was treated for worms, fungal/respiratory infection but nothing more than that. I believe that the issue is that he looks and behaves perfectly fine during the day hence the vets can’t really tell if there’s something wrong. I was also told that due to the size of the bird, it would be dangerous for any further examination. I would love to take him to another vet to check but I live in Cyprus and there’s only a couple of them hence my last resort is the internet. I have some videos I could share if you would like to have a look. Hopefully you can help! I would be forever grateful!
