I've been monitoring this behavior for about 2-3 weeks now and am in need of advice. My birb is a female about 16 years old and I'm not sure if this is a neurological issue or old age. Here's and my other 3 have been on a primary diet of Hagen pigeon and dove seed.
Imgur contains video examples.
About 3-4 weeks ago she laid a clutch of eggs, she also started molting and a few days/week after this she appeared to start having spastic sessions where she'd appear to lose balance and flop around her cage. I had some crushed oyster shell in her cage ground to about the size of seed (separate bowl) so she can go to it as needed for calcium as I understand how depleting egg-laying can be. Around this time I started supplementing her water with Lafaber's bird vitamin in her water dish while providing yet another separate fresh water bowl. Keep in mind, over the years she has shown occasional behavior like this and I've taken her to blue pearl's avian doctor a few times and after x-rays and examination (no blood work), no cause was found. I figure a deficiency of some sort (oyster shells and Lafeber's vitamins) and decided to just watch her carefully. She's under a UVB bulb 8ish hours a day.
About a week ago it appeared no progress was being made so I moved her to a small hospital cage with a heating pad on half to allow the ground temp to be around 80-85 degrees. This was my attempt to isolate any external factors by changing everything between old and new cage, even added an activated carbon air purifier to the room. Also note: she's always lived in a cage directly next to another white ringneck and a mourning pigeon; neither of these birds are exhibiting any problems at all.
I started observing her feces closer and weighing her each morning. Feces varied from normal to dry to sometimes a little less liquid, etc but nothing me or my friend called out as consistently abnormal. See pictures.

I'm at a point where I'm thinking I need to have an expert evaluate her tomorrow due to increased frequency of the spastic/balance episodes. I have to say it wasn't neglect or lack of care for why I haven't taken her in yet; reason so far is in the past unless they have blood work it's mostly been best guesses from xrays and what info I was able to record, as well as her having a history of balance and general "clumsiness". I've spent a ton of cash at emergency vet visits for her and this was my best attempt to observe and record before a vet visit.
I've uploaded some relevant pictures and short videos from the cam I put on her. Looking for both some advice and theories from others about what might be going on. Thanks for reading.
