If you want it as a nice pet I would go with just one. I have just one and my friend has just one and they make a much better pet. My friends bird is more of a pet then mine but mine had a bad histroy hers didn't. Her lovebird knows tricks it even pretends to floss his teeth it is soooo cute, all it wants to do is be with someone and sit on thier sholder. One bird defenitly makes a better pet.

They can be mouthy but its not that bad, if you need some quiet time just cover the cage and they will stay quiet. On really nice days when there is no breeze I will put his cage outside and he sits and talks to all the wild birds, its his fave thing to do.

All I can say is do your research and if you think a lovebird fits into your lifestyle then get one
