My female yellow has a large bulge in her bottom. I believe it might be egg binding. What canI do?
If the bird is straining, pumping her tail up and down, having labored breathing, puffed up and generally looking bad, then it may be egg binding. You would need to take her to an avian vet or emergency clinic that sees birds as soon as possible. The abdomen can get larger just before she lays an egg, but she should not be showing signs of distress unless something is wrong.
