Hello, it's me again. So I've got this 2 months and 3 weeks old baby tiel. I've never owned a tiel this young, so I got a few questions about her behavior. She normally sits around quietly, occasionally eating and drinking. She doesn't really care for scritchies or affection even though we offer her that daily. She does this weird thing where she suddenly goes nuts, flying very fast and aggressively, occasionally screaming (she doesn't scream in flight normally). Then she lands on her cage and starts flailing and hissing with her wings wide open. She even did this upside down hanging from the cages wall. She also did this much lower on the cages door and almost fell down. Soon enough she returns normal and starts eating. We yet don't have any toys for her to play with, only some cardboard rolls which she doesn't care about. Is she just throwing a tantrum or should I get worried? She also gets to be outside of her cage pretty much all day long.
