Hi Ashley, welcome to the family. How long is a few months? If your grey bites your ears, I wouldn't let him on your shoulder. There are oodles of threads here about how to interact with your grey when you first bring them home. Each grey is different. They trust you when they become comfortable and confident with you. When they know personally that you wouldn't harm them, just like then you know you can trust a person, it's a feeling only you can realize. Read and enjoy. Ask any questions you have and when you get a chance we would love to see some pictures of ----- What is your grey's name??? Hope to hear more about your grey.
