Just got back from the vet! They still don't seem convinced of AGY since she's doing better now and doesn't seem to have any other presenting symptoms, they think that the vomiting could've been from whatever discomfort was happening with her feet (she had a little bumblefoot spot on the area where her dislocation was, could be from the weird way she sits on her food bowl also).
Zim also has always had some strange issues with the feathers around her eyes since she was hatched, but its been a bit worse on her right eye lately so they gave me some broad spectrum antibiotics to see if that helps that (could've also been part of the discomfort that caused the vomiting)
Also they trimmed her nails and because of how rowdy she was the sander accidentally nicked her feet a little and gave her a few tiny cuts, the vet said it shouldn't be a big deal but to keep an eye on it 😕 Little concerned about that, but I just cleaned her perches to limit any kind of infection or anything. Otherwise she's resting up after all that with her siblings right now, poor thing.
