From what you're describing it sounds like 'wry neck', but let me go over a couple things:
Torticollis (wry neck) may occur in birds infected with Pasteurella bacterial infection.
A bird may be a chronic carrier, living with one or multiple symptoms; however, many birds that are infected with this bacteria progress rapidly with a high mortality rate.
When the middle ear, cranial bones or meninges are infected, ‘wry neck’ (Torticollis) is seen.
Treatments include antibiotics such as Sulfonamides or in some cases, Penicillin. Be sure you have an experienced vet since Sulfas have toxic levels.
Other bacterial infections that may cause similar symptoms are:
toxicities can cause a loss of balance and restlessness in some birds, as well as the more common symptoms such as breathing difficulties, open mouthed breathing and so on.
Zinc and other toxic metals or substances can be ingested slowly over time when toys, clasps, chains, links or even cages are chewed on or played with. Other poisonings occur when the bird actually swallows a toy, link or piece of one. Watch out for bell clappers for instance.

Good luck with her - and please check back to let me know how you and your little one make out ok? What's her name?
These days, with birds growing fast in popularity as in home companions, many DVM’s are quite experienced and able to see and treat many birds. If you have a pet store that sells birds or know of any bird breeders – ask them who they use for their bird care.
So much information is flooding the net these days about what to feed a companion bird, whether a budgie/parakeet, cockatiel or marvelous macaw, it’s sometimes difficult to wade through the junk science, old wives tales, well meaning owner advice or just plain dangerous suggestions.
The vitamins from pet stores can sometimes cause more problems than they solve. I really wish they weren’t allowed to sell them (or the supposed antibiotics or sprays or mite protectors).
It’s generally recommended that most of today’s companion birds have a predominantly pelleted diet. Pellets have been continually updated since being introduced to the market years ago and today’s formulas are better than ever.
Supplementing this diet with fresh foods every day is ideal and many owners find they can re-introduce seeds - in limited amounts (perhaps once or twice a week) without the bird refusing the pellets overall.
Whole grains, dark leafy vegetables, fruits and legumes. Include the colors orange, yellow , green, plus reds too! Think sweet potatoes/yams, squash, melons, oranges, peas, chard, beets and others.
Brown rice, quinoa, whole wheat couscous and natural, whole grain pastas are great choices.
Limit fats, especially the kind from animals. Good fats are most plant fats like soy, olive and canola oils. No fried anything
Another thing you can try is all natural, human baby food. Stick to the orange colors.
They can be mixed with tiny pasta or rice, whole grain bread or toast - remember, be more creative than the bird is stubborn.
As odd as it sounds, birds don’t need much, if any vitamin C. It is a water soluable vitamin which means it passes out of the body after the body takes what it needs and C is available in a wide variety of both fresh and processed foods given to birds.
Go for the pellets to avoid overall problems - try the uncolored, plain type at first, but feel free to get creative. Whatever she will eat .

Vitamin A/Beta Carotene, on the other hand, is frequently found to be deficient in birds. This is a fat soluble vitamin which means it gets stored in the fat cells of the body, so it’s possible to overdose on it. With our companion birds though, too little is the situation most often encountered.
