I have a year old male, Toby, who has always been in good health. Last weekend he started showing signs of lethargy so I put him aside near a heat lamp with some vitamin-enriched water (soluvite-D) and feed. He started to eat less and less. His poops started turning into 100% urates. His weight dropped dramatically--he lost 7g just over this weekend and is emaciated, now weighing only 34g. Live mealworms catch his interest for a short time, he'll eat a couple, then get tired and go sit in his corner fluffed. He shows no interest in food. Suspecting some sort of bacterial problem, my vet put him on amoxicillin when I took him to the clinic on Friday. That didn't seem to have an immediate effect so I brought him to see a different vet today who noted that Toby's intestine could be felt through the skin of his abdomen. His breastbone is very prominent. The 2nd doc showed me how to feed via crop tube and so I was able to get some calories and fluids into him today (finally!). He's only pooped a few times this afternoon, only one poop I could see actually had fecal matter in it. He'll rest for about an hour after the crop tube feeding, then perk up for a little bit, even calling out to his brothers and walking around his cage trying to get to them. None of my other birds are showing signs of illness. What could it be? His symptoms match several possible diagnoses: White droppings consisting primarily of urates Lethargy Weakness Lack of appetite Fluffed appearance Wasting (from lack of appetite) Gizzard obstruction? Ulcerative enteritis? Kidney disease? My vet is mostly experienced with psittacines, not gallinaceous birds. A specialist vet might have answers but it will cost me hundreds to find out.
