Sometimes its hard to tell birds what to do. They just like
being on our shoulder's closer to their mates.. your head.
lol. but if being on your shoulder is really a problem take
her off and have her on your arm. But being on our shoulders
or laps is just mor ecomfortable for them. If she keeps
trying to go up to your shoulder then dont let her, if you
dont want to. I allow any of our birds on our shoulder. But
be more wary with the more larger parrots being on our
shoulders than th ebirds from finch size to conure size.
Just give her some time. You;ve only have her for a week
now, so just have LOTS of patience. It will take a while for
her to get use to you, and probably take you a while longer
for you to get used to her.
