Hello everyone. We are so worried about our girl, and hope that you can help us help her. Our Sadie is about 1 1/2 years old. She is usually our friendliest bird. She comes running to the door and "talks" to us whenever we go out back. Lately though, she stays to herself, and has even taken to roosting on the nest box, alone, rather than with her four sisters on the roost. This morning, I noticed that she's making a gurgly sound when she breathes. She seems very lethargic. Still walking and eating, but very sleepy. When we picked her up to check her over, we found no visible signs of injury, but she greenish watery stuff fell from her beak when she opened it... as though she was salivating. She is resting in a box now, wrapped in a towel to warm. And is gurgling with almost every breath. Any ideas?
