I have a 2 1/2 year old golden buff that suddenly can't seem to stand or walk. It appears to be an equilibrium issue. She uses her wings to keep herself sitting upright. I took her to the vet, but they don't have any answers. She's been in sick bay for 5 days now with no improvement but is still eating and drinking when I hold it up for her. Today I found an odd gob of tissue in her cage that is kind of gizzard shaped? I'm guessing she coughed it up, but it's rather big! It was clean, so I'm guessing she didn't pass it the other way! Does anyone have any idea what could be wrong with her? She can't go on indefinitely not being able to stand up!
