She should be on a cockatiel diet instead of parakeet. I would try to offer her some fruits or veggies. She might enjoy them, my bird loves apples and bananas! Spinach or broccoli would be good too. How old is she? If she is still unwell in the a.m. a vet might be best. I'm going to bed now, 2:00 where I live. I will check back in the morning. Good luck!
