I brought Chixsie in yesterday because she was poofed up and acting weird, the way a sick bird does. She wasn't eating so I fed her (with a syringe) yogurt, baby food, vitamins, and water. This morning she was gasping for air and vomiting a yellow liquid. I thought she was going to die. I took her outside and held her, trying to let her have some peace. She continued to vomit, and then stopped. She was still gasping for air and I brought her back inside. She stopped gasping, and even flapped her wings a bit. I fed her some yogurt, sugar water, and vitamins. I stopped when she was gasping again. She is pooping, kind of like a diarrhea. I put her back in her cage so she could rest. Is there anything I can do?
