This is my 3rd week home with my Cockatiel Cherry. I had bought her from a bird store at 7weeks and was not completely weaned yet. So I have been giving her 30 ml of formula a day with seeds and pellets in her cage. Today, she had 10ml of formula this morning and tonight she refused completely. I am worried. She doesnt seem to want to drink or eat her food at all tonight. It scares me.
