Ohh that article from Greg Glendell on hand raising is really interesting and to me it makes perfect sense to let the parents raise the bird to feel normal and stable.
Congrats too jparrothead on the conure, and by the way I've had a GCC for about a year and 9 months and she's 2 years old and GREAT!
GCC's are very playful, almost dog/cat like. My BeBe will love to roll over onto her back and I wrestle around with her on her back.
I hear people always talk about this nippy thing, but from what I can tell it's just that they like to play and chew, like a puppy does. There are times they do like to wrestle around and play a little rough, this is something you'll have to learn.
The GCC is so intelligent, just remember this is a big parrot in a small body, so treat it the same, with love and attention!
Oh and make sure lots of people spent time with the bird so it doesn't start bonding to one person, that is where I've seen BeBe get nippy, but soon overcomes it, then if you see your bird starting to get nasty towards someone, you can over come it quickly by allowing that person to spend more time with the bird.
BeBe will act nasty towards my family sometimes, and I see now, it's only the birds way of saying HEY you don't play with me, sort of like a kid acting up, but once you spend the time, the kid starts acting nice again. After all how is a bird suppose to tell you, that you aren't being nice to it and giving it time? Well it nips at you is what I see...
Oh and as far as noise, don't worry a GCC is not loud, this isn't a Macaw, LOL... But they will yell for your attention, so if you don't want to give it, then teach the bird you only come around when it's quiet, meaning if you step out of the room, don't come back until the bird is quiet for 10 mins in the beginning, then slowly increase it. Soon your bird will realize it needs to be quiet to get your attention...
