Hello, I just changed my birds cage to a bigger one. Including my cockatiel- Cloud. And my Budgie- Asher. My cockatiel has not been as vocal as usual and not very friendly. He's 18 years old. I've had him for three years. I was wondering if the change of cage could be bringing on this type of behaviour. Or if he's just in a bad mood. He's been living in his old cage for the 18 years of his life. Thanks!
