I agree with randy , budgies need to go to a qualified avian specialist vet, sometimes they are hard to find and travel is expensive, I myself travel an hour and a half each way to my avian vet. But in the long run they are the best treatment and advice. It does sound like your budgie has some trauma or neurological damage, The only real solution is an avian vet for the correct outcome and treatment.

I understand , sadly vet visits do add up and it is hard but we take these little ones into our care and in doing so are responsible for their health and care. perhaps you can start saving account for Budgie Health care, you will be amazed how quickly it will add up and be a huge help for future misfortunes.
I hope she is better, perhaps give her some food dishes and water on the bottom of her cage and make some platforms for her to land on and stand.

Karma to you for taking your sweet budgie to the vet.
Many Budgies live a life using platforms and ladders to perch.
I agree with you in separating them from each other if her friend gets to pick on her, they can still have time together but only when you are able to supervise them in case you need to help out.
The ramps are a great idea, place her food on a flat surfaced plate or bowl as well, be careful will supplying a bed as she could come into condition having this and then egg laying could be a problem. As long as she has a soft flat surface to sleep on she will be fine. My guys sleep on a rat double ladder bridge perhaps you can get one of these and cover it with some soft material she can then lay across it. Good luck I am sure you will be fine and so shall she.

Can you post a picture of the cage you are thinking of?

That sort of set up looks great and would be fine for your budgie to live in happily I am sure. Can she walk around at all?

That is wonderful how she managed to climb up and perch, she definitely has some sort of nerve or neurological damage causing the twitching by the looks. make sure she gets fed plenty of good healthy foods, greens, egg and biscuit mix, with time her condition might improve as her body and nervous system gently heals. Keep up the great work in looking after her.
