Generally, birds are more suitable to live in deep mountains and forests. If your home is in a mountainous area, it will be easy. Before you release them, check whether these two birds are healthy. If they are healthy, it is better for them to go back to the deep mountains and forests. Birds are used to a free life. Banning them is very bad for you. If you don't trust them, you can send them to a temple like Wuxia Temple, and the monks will set them free. I have experience in this field, so don't worry too much.
