Hi Goldie. I know you thought you were doing a good thing for him but that stuff from the pet store is, for the most part, worthless as you can see. About all it will do is cause them to build a resistance to real antibiotics, making it much harder to cure them when they really need something. If the diarrhea has really slowed down, that much is good. But because you are adding something to the drinking water, (which is a huge no-no with birds) he has probably cut way back on the amount of water he is drinking. Diarrhea doesn't just go away and that pet store junk is not going to cure it either. He is probably well on his way to dehydration. You need to get that stuff out of his water, wash and scald the dish and give him plain, fresh drinking water right away. What you are seeing are classic signs of a very ill bird. Not only that, it's a bird that has been ill for way too long without proper treatment. One of the strongest instincts our birds have is to mask all symptoms of illness or injury from us, for as long as possible. When we finally see symptoms, it's because they are too weak and too ill to keep up the pretense any longer. Sitting with feathers fluffed, sitting on the cage bottom, sleeping an inordinate amount of time and any change in the droppings that lasts more than 24 hours and cannot be accounted for by diet are serious alarm signals. I cannot diagnose for you in this format. Not even a Certified Avian vet could do that. If you will not delay any longer and get him in to a proper vet, there is a chance that a simple test on one of his dropping samples to pin point the problem, then a 10 day course of real, full strength oral antibiotics, (not in the water) might just fix him right up. If you don't already have a good avian vet, I'll give you some links to help with that. In the meantime you need to make sure he does not get chilled. The closer we can keep an ill bird to 80F, the better. Cover the top and 3 sides of his cage, keep him as quiet and stress free as possible and get on the phone to a vet. I'm not going to waste more of your time asking about diet. I will just tell you that if he has not been getting anything but seeds, he is not in good health at all. He should be getting fruits, vegetables. leafy greens and much more. I'll also give you some links to help with that but for now, the little guy needs a vet, "yesterday". I hope this helps and I hope you will find him the help he needs right away. If you need anything else, just let me know and I'll keep the little guy in my thoughts. Patricia
