Single bird vs pair — the eternal debate

I work from home so my lineolated parakeet gets tons of attention, but I still feel guilty during meetings. Would getting a second bird be good for Lucky or would it backfire? I've heard horror stories AND success stories. What's YOUR experience?

Birds are basically tiny dinosaurs with attitude. My Basil has me completely trained at this point.

Okay but counterpoint — what about birds that are the complete opposite? My lineolated parakeet breaks every rule lol.

I've done a ton of research on this because my lineolated parakeet had the same issue. Here's what I learned: the most common cause is jealousy of a new person, pet, or even object in the home. What worked for us was using a shower perch so they can bathe with warm mist. I also started switching to a natural cleaning spray like F10 and noticed improvement within a week. It's a process but it gets better.
