It will vary depending on both the bird and the breeder.
Stitch was hand-raised and my breeder's favorite (which he had initially selected to keep as his own companion parrot to live in the house) so he was very good at stepping up etc when we got him. When he arrived he flew to a perch, sat there for a while then immediatly stepped up when asked. He also went willingly into his new cage, and after just 1 day he was showering with us in the bathroom (the breeder had taught him this, so it was very easy and something Stitch loved).
Leroy on the other hand was a parent raised aviary bird, and had no taming done at all, and very little contact with humans at all, apart seeing people through the aviary. He was also 9 months when we got him, so not a newly born baby either, and thus not so easy to handle.
We (I) had to grab him out of the carrier and put him into his new cage, and after that a long process of getting him to trust us started. Progess was fast to begin with, he took food from us within a week and we had him targeting by two. Then he flew into a wall and decided it was all our fault, and decided that he shouldnt trust us for a long while.
Months of training later he was a completely different bird, and today he is doing great. He steps up, knows flight recall, targeting, turn around, dance (repeated nodding) and wave. He
oes NOT want to be grabbed though, no matter how much I try to achieve that. He actively seeks our company and wants to spend time with us. Its very heart warming to see

This turned into a lot longer post than I had thought, but my point is, it will depend on alot of circumstances. If you suspect the bird isnt very tame, put him into the cage immediatly and start working on trust. If not it might go very smoothly.
Either way, I am sure it will work out fine for you, as long as you are patient.
Oh and stick around on the forums!
