Hello Barbara and welcome to the family, so glad you could join us and we look forward to hearing more about you and your new baby grey.
Don't worry, I don't think he will change his mind about bonding with you after the hand feeding is all done, I think you are set for life.
You must be new to parrots if you had to do a lot of reading to find out some of the things about greys that you didn't already know and you will find out a lot more by continuing to read thru all the threads. We have tons of good information that will help you in the coming days, weeks, months and years of this newfound friendship. If we can be of any help all you have to do is ask.
If you have some pictures of this new grey you would like to share with us we would love to see him/her.
