Okay so I had my green cheek for over a year now. He lets me pet him, but I have to approach him slowly or else he backs up a little bit. I think if I move a little to quick he thinks I will hurt him. Whenever he's on my chest he always kissed me, nibbles on my necklace and moves his head towards my fingers for me to scratch his head. I also have a cockatiel that lives in the same cage as him and they seem to get along just fine, but could also fight. When they fight there is no blood included, just pushing eachother off a perch. I also share my food with him sometimes, but I just feel like my green cheek doesnt trust me all that well. Does he not trust me or just doesn't like me?
