I have 2 cockatiels, a white male with red eyes, and a black female tiel. They both used to live in along with a little zebra finch in a small white cage. The cage was wayy to small for them so to make up for it, i let them out and free roam my room any way they like. But the problem still arose that i couldent let them out when I was away. I used to let them out when i was away but i stopped doing that after an incident where my female cockatiel got her head stuck in a door. So i finally decided to get them a new cage, A big cage, one that could house a cockatoo comfortably and set it up for them. The next day, they still wanted to be let out and would cling to the side of the cage until i opened the door. The birds also dont seem to miss their old cage witch i guess is nice. They have a love/hate relationships with cages, where they always want to be near it but never inside unless hungry or tired. Is there any way to make them happier with cages? maybe new toys?
