Knowing what’s wrong is half the battle and this is great news, hardware disease is nasty and can have long lasting effects. Poor girl though, I have a few picky eaters like that and it’s frustrating when they’ll literally starve themselves rather than eat.
I would suggest once she’s back to a healthy wait occasionally mixing other feeds with the one she likes to help her adjust to something that’s different incase you ever end up in a situation where the local feed stores don’t have the right feed in stock or there’s a bad batch. One summer all of the purina flock raiser “what my birds prefer” at every store in my area was contaminated with mold so I had to switch to nutrena. The weird thing about nutrena is sometimes my birds absolutely love it, other times they’ll go hungry too rather than eat it.
