Hello and welcome to the family, Kathy, glad you could join us and we look forward to hearing more about this special grey you have coming into your life. I am always so in awe of anyone who can open their heart to one with some type of handicap as this one has.
You have chosen an excellent book to read on greys, that is the first one I would recommend to new grey owners, and it is filled with valuable information. You will also find lots of useful information here in our many threads on various topics, read thru them at your leisure.
You are correct that you do not spend any more time with them as babies that you cannot maintain for the rest of their life, they get used to it and then if you cannot keep it up behavior problems can develop.
Thats nice that you can work out of your home and he will love having the company and you can have him out of his cage for as long as you like, he really only needs the cage for when you are not at home and at night.
I can tell that you are very excited and you should be, it is like bringing home a new baby, and I am very happy for you, I know you are going to really enjoy this bird and love it with all your heart.
If you have a picture you would like to share with us we would love to see it, we like to admire the babies, they are so adorable.
