with Randy and Cathy
As long as you spend as much time as possible with her and she has plenty of good foods, she'll be fine. It's okay to give her a little more millet than usual during this time to get her spirits up.
Move her cage (it it's movable) to where you are so she can begin and strengthen her bond with you as she gets over her grief.
I'm sure she'll be fine! You can also put probiotics, like organic, unfiltered apple cider vinegar with the "mother" in it in her water to boost her immune system. Hope your little girl feels better!
