From the online Avian vet:
I'm sorry that your question wasn't answered in a timely manner. Thank you for the excellent photo. This posture is consistent with neuropathy associated with malnutrition as well as spinal kyphosis. What have your birds been eating, please? Seeds should comprise less than 20% of their diet. A diet of mainly seed and nuts has excessive fat, carbohydrates, and phosphorus; marginal protein; adequate vitamin E, and are deficient in amino acids, calcium, available phosphorus, sodium, manganese, zinc, iron, vitamins A, D3 (necessary for efficient absorption of calcium), K, and B12, riboflavin, pantothenic acid, choline, and available niacin. Ideally, a balanced pelleted diet such as can be found here:

www.lafeber.com/pet-birds should be fed as well as hard-boiled egg yolk, pancakes and cornbread, the tops of fresh greens, dairy products such as yogurt and cheese, fresh fruits such as apples, pears, melon, kiwi, and berries, vegetables such as broccoli, carrots, beets, asparagus, cabbage, sweet potato, and squash, and even tiny pieces of meat.
Please respond with further questions or concerns if you wish.
My reply:
Hi Doctor, thank you for answering. She is on a pellet diet, not seeds. Their food is:

However, the ER doctor noted she is on the thin side. Is the condition reversible with dietary/supplement changes and also, can the onset be so sudden? She developed this posture in less than an hour.
His reply:
Thank you. I'm pleased to hear that they're eating well, although I do need to consider that the current batch of pellets may be lacking in a micronutrient(s).
No, I wouldn't expect such peracute (sudden) postural change due to malnutrition or spinal kyphosis unless a pathologic fracture occurred in her spine. That's usually due to an imbalance in serum calcium/phosphorus (rickets). I would X-ray such a bird and perform basic diagnostics in the form of blood and droppings testing. Consultation with an avian vet (
