EAGLE UPATE APRIL 2023:
Its been 5 months since my boy has been sick. He has gotten a bit better and finally put on weight were he is at 90 grams. I would say he is about 60% better, still better then before, but its been a slow recovery where he isn't 100% yet. Its been 5 months with this. I still give him certain homemade foods and water with vitamins via a syringe, just to make sure he gets these vitamins in his belly, he loves my homemade food.
I do have some questions though for those more knowledgeable then me in this area. Ever since his ilness, I've noticed he is still very weak, and at a lost of equilibrium/ balance, and has not grown any new flight feathers, I keep them trim for safety reasons. His grip of my finger when I touch him daily is very weak, I need to support him, with 2 hands so he doesn't lose balance. I've noticed he doesn't have the strength to crack open sunflower seeds, the smaller millet seeds he can handle. I do have to trim a tiny part of his beak every 2 weeks since its growing at a fast rate. He is still puffy with his feathers where he seems cold, but I can tell he isn't cold and his tail isn't shaking from cold. I live in Florida, its hot here daily, and my house is never cold (mid 80s). He still spends 80% of the day sleeping, and eating. He does like to preen himself.
He was on Itraconazole, for 5 weeks and that helped big time. Any other opinions or information is appreciated Thanks to everyone interested!
