Hello Scott and welcome to the family, so glad you have decided to join us and we look forward to hearing more about you and your rescue.
I commend you for taking on this task, it is not going to be an easy one but it is one that will be very rewarding when you finally earn the trust of this grey.
I read your other post where you tell us a little about this bird, how sad it was treated this way and now it is plucking itself, you may be able to turn that around but only time will tell.
Please read thru the many threads for lots of useful and helpful information and do not hesitate to ask any and all questions you may have and we will strive to find you some answers and help you in any way we can.
If you have some pictures of this grey you would like to share with us we would love to see them.
