Not that I know off ...
EllenD already said it is "normal" for breederbirds to act a bit disturbed (at first anyway) when confronted with a real parrotlife-
and although Sunny has never been a breederbird as far as I know...
(but was in a waaaay to small cage by herself most of the day for far tooo long )
she got a larger cage once she arrived here: and it took her a full 4 months to finally visit the cagebottom (afaik she went there only once and only because she sees the greys chickenscratching and having fun on that level in theirs) and she got to the other upper corner only 2 months ago (that is about 8 months after being put in this particular cage...) because I placed a bunch of willowbranches/twigs in such a way she had to detour to reach the waterbowl.
She mostly sits in one corner of hangs from the ceiling in another ...
she is kind of "insane in the membrane" that way.
I was expecting her to climb around a lot and be curious, but no... she sits and stares (or hangs and rocks herself) unless I ask her to do something, most of the time.
She is getting more and more into gnawing branches and chattering to herself (or the TV) but it is a slooooow process.
(She has *no* clue what to do with toys)
Java has not been around you that long, is he?
(
I met Sunny about 10 months ago, and I am happy she is at least making progress - a friend asked to see a picture of her and I was shocked when I found the one taken in januari - she really changed a lot and I did hardly notice.)
Anyway- if you are doing something wrong... then I am making the same mistake
