Thank you for your post! I will just see how it goes for the next couple of weeks. I hope she settles in with the group. I have the space and may be up for getting two more in the future, but don't really feel ready at the moment.So here's the issue. Integrating 1 bird is the most difficult integration. But if you add 2 birds, they're just going to stick with each other, so you didn't "solve" anything.
I would say as long as you 1) want more birds and 2) have the space to quarantine (if you wish) and properly integrate them, then sure, go for it, but don't get more birds just to try and give her a friend.
