I adopted a Timneh Grey in February. After 6 weeks i noticed his droppings didn't seem right, they were getting rather watery. We took Sydney, who is about 18 month old to the vets as we had only lost a Grey last October to Proventricular Disease. The vets took x-rays and did full blood count and ruled out Proventricular. The results came back as showing he was lacking in protein, had malnutrition and also concern that he had zinc poisoning from a toy in his previous cage! There was some improvement after the first lot of injections, but starting going backwards before finishing the second lot. We've had his zinc levels checked again and are still awaiting results. Have had all his bloods checked again and now his protein levels have dropped very low. Advised to give him lentils, kidney beans and pulses etc to help with protein, also to get him on a pellet diet. Sydney is still drinking excessively and his droppings are'nt good. Have been told by vets that diabetes is very rare in birds and that again the treatment would be to get him on better diet. Vet says the next stage now would be to do endoscopy and kidney biopsy, but don't know if I can put the poor fella through much more! Anyone got any advise they can give me please?
