This is about my cockatiel's behavior. Although it has only been 1 day since I got my new cockatiel(also, this is my first pet parrot) but it keeps on walking back and forth in front of the cage door and climbing the top of the cage which resulted in it falling and hurting itself although it is new. I suspect it is because it wants to come out some more it has been bleeding and I think lost quite a lot of blood which makes me worry. I THINK it is a blood feather but I am not at all close to my cockatiel yet so any suggestions?
