So Lemon is doing really good with interacting with me as long as he is inside his cage. He will step up, play with me, and preen my hand but only when he is in his cage. When i open the cage and let him fly out on his own, he gets scared and doesn't really know what to do with himself. He will just land on something and sit there. if i try to approach him, he no longer wants to step up onto my finger. it seems that he loses his trust with me when he's not in his cage. i've never forced him to come out of his cage, but even when he comes out on his own he's always very timid and nervous. how can i show him that being outside of the cage can be fun and not scary?
