I finally got to a board-certified vet and she is amazing. I drove out of state today to see her (Exotic Bird Hostpital in Jacksonville, FL) and she was fantastic with the birdies.
Snowflake's doing great, but Lucky, my eight-year-old, definitely has liver disease; she diagnosed it on the spot. But after his tests got underway, I learned that he had elevated levels of uric acid, meaning kidney trouble. He also has high cholesterol and large amounts of fat in his blood (even though his weight is healthy with no fat pockets on his body). So she asked me to leave him there for hospitalization for the next few days.
I bought them toys for their travel cage, and Lucky will be on fluids and cherry juice for the next two days to flush out his kidneys, as well as milk thistle for his liver. The doctor will keep in touch with me and let me know how he's doing. I was totally unprepared for this. I knew he must have liver problems, but was not expecting kidney trouble or hospitalization or anything. I left both birds there to keep each other company.
I've never been through anything like this and I miss my birdies; it's so quiet without them and they're hours away from me. I'm hoping he will be alright and that we caught these problems in time. I'd love to hear any stories you'd like to share about your birds or these specific diseases, any experiences like this. I hope he recovers without problems.
What this has taught me is the importance of having a *real* vet to look at my birds. I would not have caught any of these things if it weren't for the wonderful people on these forums, and I am so appreciative.
