My cockatiel suddenly hates her cage
When I have my cockatiel is out of her cage, she usually wants to get in again after 2-3 hours to eat and drink, and I usually close the cage after her.
But she do not wish to go inside her cage the past few days, and I have to force her inside. When she gets in she eats, drink and then stand next to the cage door, waiting to come out. She has been biting on the cage doors.
She has never done that before, and I'm very worrying. Am I doing something wrong?
She has plenty of room and toys that I switch every 2. week to entertain her.
