okay everyone I have been working with my female lutino cockatiel for awhile now , while she will willing step and does not seem to be terrified of me, she is scared to come out of the cage on her own. I can have her step up on my finger and take her out of the cage but as soon as the millet is gone she quickly retreats back to her cage. She seems to want to come out and if I leave the door open she will come to the door but won't dare come out. How do I get her to come out on her own ?
