Yes, egg binding should be a consideration but because she just laid hypocalcemia and other nutritional imbalances are more likely. Nutritional imbalances are a common cause of illness in our pet birds and their repercussions appear when egg laying depletes the hen further. What has Pinta's diet consisted of, please? 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.
Do you have an avian vet (please see here: www.aav.org) available that can see Pinta and treat her intensively with injectable vitamin and mineral supplementation as well as tube feed her a balanced but rich convalescent formula?
