Hi! My name’s Courtney and just got my new bird Saturday evening. I have done a ton of research on Cockatiels and how to tame them. However, I feel I either forgot everything when we brought him home or I just can’t remember. He has barely made a peep. He seems super sweet and was hand raised. But he hisses if he gets out of his cage. He let me pet his neck and head when we got home with him but since then has been too afraid. If I get close he hisses or opens his mouth and backs away. He will eat his food, but haven’t seen him drink any water. I want to clean some of the perches and parts of cage, as he’s already made a mess but he won’t come out. Should I force him out or just leave him in there while I try to clean things? The past 2 days I’ve been sitting by his cage, singing to him and talking to him. I’m trying so hard and don’t want to screw this up. Any advice would be great! Thank you!
