Greetings, We bought our very first budgie which is a male and about a year old. Sometimes I feel that he just looks really bored. We are normally all out of the house during the weekdays. Is it a general rule that two budgies are better than one? IOW does having two budgies dramatically improve their quality of life? If I do get a second budgie should it be another male? And should it be the same age or is a 3 month old okay? Thanks David
