I got this male cockatiel last Saturday and it's my first cockatiel. I had a budgie but it was my gf's so already used to humans around. Anyway pet shop owner said they are around 1 years old but I think he kind of lied about it. He's a scared one. Well other birds in the pet shop were scared as well. At first I tried to get him on my hand without stressing him but it didn't worked. I looked online for help. Everyone was saying leave it alone in cage for a while, don't try to get near it unless feeding&cleaning. Let it get use to you and environment. It's been 5 days and he was kinda chill, not eating much but still eating, resting etc. and today he started to freak out in cage like he wants to get away. I thought maybe he's stressed being in cage so I got him out for a while. He just flew all around anxiously. So I don't know what to do. Should I just let him be for a while. I really need help. Sorry for my poor English btw.
