Hello. I'm so sorry your little guy is having a problem. If I can get some more information, I'll sure do my best for him.
You compare it to a possible stroke but other than the flapping around, you didn't elaborate on how he is acting so far as movements, etc. Has he lost use of either or both legs or feet? Is he walking and perching or is he sitting and/or laying down?
Exactly what do you mean "giving him vitamins? What are you giving him and did you put it in his drinking water? If so, you need to get it back out, wash and scald his dish and replace with only plain fresh water.
Exactly what are you doing to "hand force" fluids?
He is over 12 years, correct? How old is he?
Are you positive it is a male bird?
Please tell me all about his usual diet?
Okay Charles. Due to his age, there is certainly more than one thing that could be going on. However, what jumps right out at me is the onion. It's toxic to birds, especially if it's raw. He has not been on a complete diet so he is very likely to have some liver damage that may or may not be showing up yet. A diet, for a Tiel, should not be more than about 25% seeds and seed products. He should have been getting a good pellet mixed with his seeds. His seed mix should not have any sunflower seeds in it as they are very high in fat. And, he should have been getting a big variety of vegetables and leafy greens. As for the sunflower seeds, they are not toxic or anything like that but they, and millet, have such a high fat content they must be given very sparingly. Rule of thumb with them would be no more than about 5-6 seeds per day, per bird. A high fat diet leads to fatty liver disease, Hepatic Lipidosis. Even if you have had no visual symptoms yet of liver problems, he may very well be suffering from it. The added strain of a toxic food may be what it has taken to "push him over the edge", health wise. This is really terrible timing, right here at the holiday unless you already have a relationship with a very competent avian vet and you can get in as an emergency. He really needs to be gotten to a proper vet, sooner rather than later. There is not much you can do for him at home, other than supportive care. Keeping him warm is good. Keeping him quiet and stress free is very important. The more liquids you can get down him the better to maybe help flush his system. If you can get a few drops of Pedialyte into him the same way you are doing the water, that would be great. It will help keep him hydrated and will help his electrolytes. Do not replace his water with the Pedialyte but you must get those vitamins out of the water right away. Wash and scald his dish and give him only plain fresh water. Anything like that added to drinking water can cause bacteria to grow very quickly. It is never advisable to add anything to our birds drinking water. It's going to be hard, since he is going to be very set in his ways as respects diet. But if you can get any steamed veggies into him, (carrots, peas, corn, yams, etc.) or if you can get him to eat some plain cooked oatmeal, maybe some hard boiled or scrambled eggs, something that will help offset the toxin in his system, it may help. But the botXXXXX XXXXXne is, he really needs to get to a vet. Just in case you don't have one, I'll give you links that may help but unless you are already established with one, it may be hard to get in today. Most really good avian vets do have 24/7 emergency clinic services available. Whether they will take an emergency that is not already a customer, I can't guarantee. Some will, some will not. I don't know where you are but another good option is if you live any where near a college that has a vet school. I so hate to have to give you this bad news and I wish there was anything else I could do for him long distance. Unfortunately, there is not. I do hope these suggestions will help him some though, until you can find a vet to see him, the sooner the better. Please, let me know if you have more questions or need any further clarification of anything. I will be keeping the little gentleman in my thoughts and will hope for the best possible outcome.
