Hello Jerrysmom and welcome to the family, so glad you decided to join us and we look forward to hearing more about you and your grey.
Your grey may welcome the addition of a new flock member but then maybe not, just because you had them both and he has been around a bird all his life does not mean he would welcome another bird to take the other's place. He may not care one way or the other, if you do get another bird get something that you have been wanting for you and not just for companionship for the grey.
Take a few minutes and read thru some of the many threads for lots of useful information and do ask questions you may have. We will do our best to get you some answers and help you in any way we can.
If you have some pictures of your grey you would like to share with us we would love to see him.
BTW, what is his name?
