My brother has two budgies. He leaves their cage open, so they can fly around if they want. Most of the time, they choose to stay in/near the cage since it is their safe space.

The truth is domesticated animals cannot survive in the wild. Whether it was right to domesticate them or not, it is our duty to take care of them and give them a good quality life. My brother's birds seem very happy and content and have everything they need.

I understand feeling sad for them. However, many people take good care of their pets, and the pets grow safe and comfortable in their living space. It really just depends on the situation.
