It can be done, I know people do it, it just takes a lot of work. One thing I suggest is getting the Bird Sitter DVD from parrot University - think of it as sesame street for your parrot. It helps them by allowing them to see and hear other parrots in social situation, basically it helps them understand being a bird, something that a lot of companion parrots ESPECIALLY hand raised ones struggle with. Leaving some sort of noise on helps because in the wild silence = danger. Also, it is just going to be a huge responsibility to give him enough attention when you are home, but that doesn't ever change no matter how many birds you have

Don't despair! In an ideal world I believe every bird would have a bird buddy, but they would also have a perfect diet, unlimited toy budget, and be able to fly 20 miles a day like they do in the wild.
One thing I suggest is that while your baby is still young, harness train him. being able to safely take you bird outside opens up a HUGE door to mental stimulation for him, and he needs that. I won't get into the wing clipping debate (other than to say, research both sides! I strongly recommend writings by Dr. Steve Hartman of Parrot University in Ohio) but even a clipped bird can fly away! Don't believe me? I have had it happen and it was devastating. When a bird is startled they can fly away, even if they are clipped. Also, a clipped bird is less likely to understand the very tricky skill of flying DOWN, and will likely get stuck in a tree. I say this because no matter if you clip or not, you need to have a plan for keeping your bird safe if you take him outside, and I believe the best way is with a harness (preferably the Aviator Harness, which is by far the safest option!).
I know this isnt about having only one bird, but it is about giving a single bird the fullest life it can have. Most of us wouldnt consider keeping a dog inside his whole life, and a GCC can live 30 years!
Best of luck! I know your little guy is loved
