Hi my name's die and I have a blue and gold macaw that's about a year and a half old and all of a sudden I get back from work yesterday and he starts making these hickup like sounds and his head is all fluffed up and his wings flap alil Everytime he does alilhic up..I though it was normal but then he kept going for about 15 mins non stop and then I decided to take him to the vet keep in mind he didn't stop doing that hicup when I got to the vet we had a x-ray done and check his temperature as well as check his heartbeat and all was good but the vet said he was clearly sick due to the fact he couldn't stand sriaght and kept leaning low he also wount stop that noise after that I took him to three other vets but non know what is wrong with him...he's very unactive and seems very weak.. he barly can climb up on my shoulder when isally he will run up in a matter of 2 seconds the Dr gave him vitamins and antibiotics but has no idea what is wrong with him...please if anyone knows what this is let me know.. thanks in advance .. there are no more vets to see in my area
