Seperated from others
a few days ago I held my budgie Yellow, and discovered she was become quite thin. I assumed it's becuase the other two birds were hogging the food and leaving her out.. Yellow is also kinda bullied. So I Seperated her from the other about ten minutes ago and now she's searching all of the cage for a way out, as if she wants back in with the others. Is this mistreating her? Will she get depressed? Did I di the right thing?
