Thank you! There's no evidence of a fracture; instead, these digits are "sprung" - sprained, strained, and perhaps subluxated (minorly dislocated). The tincture of time should take care of it. We don't splint these nor is there a need for surgery. The metabolic rate of these birds is so rapid that healing can take place within as little as 3 weeks. If she's not sensing you touching it, nerve damage to that digit is likely. The nerve was likely to be stretched and torn at the same time that the tendons attaching the toe to the foot were stretched and torn. Nerves take longer to heal but can heal.
Make sure that her diet is well-balanced so she has the building blocks for tissue repair. Seeds should compose less than 20% of her 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.harrisonsbirdfoods.com or 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.
