I think you have done a wonderful job with your fids.
Kiwi has learned tricks! That is super cool. My guys only trick is watching Jeopardy
I have to agree different breeds react and act differently. I should be dissapointed Huey has not learned any tricks and I think it might be me, but then I had an african grey and a love bird who learned tricks so I think it is him.
I also think that they decide what they want to do and when they want to do it. I open Hueys cage every night and while he comes out he also decided to go back in and hang out in there.
