MrLourdes your little Lucy is looking for her new flock, she has been removed from all she knows, her siblings, her breeder. You are all she has, and she wants to know where she belongs she wants to belong to her new flock, you. You need to reassure her that you and she are forever companions. When she is more comfortable with her new home she will calm down. Talk to her, reassure her and when she trusts that you are always there for her and she knows the daily routine all should be well. My little Ana Grey would love to sit on my shoulder too but I do not let her. She has table top perches, or swinging perches in all the rooms of the house, or the back of my typing chair to sit on, not me. She is usually with me all day. Ana's breeder clipped her wings before I purchased her so she also tries desperately to fly and it is heart breaking. Ana Grey has oodles of toys to play with, a boing, a cargo net and several different perches to sit on with toys hanging from them. She has lots to keep her busy and has become quite independent. I believe so will your little Lucy once she feels safe that she is home forever with her new family. This is what I have learned with my little Ana. I hope it helps. Good Luck!
