NorthernFinch,
The other cage was basically for “isolation”, just in case she’s got something contagious, which would put your other Bird in jeopardy. But, if they’ve been in the same cage for all this time, and the other Bird hasn’t been effected, then there’s no immediate need. However, it is a good idea to have “something” standing by, just in case you need to do that quickly.
Your attention to her, certainly indicates care and concern on your part in their interests, but, I’m reaching my limit on recommendations for you. So, come on guys, you experienced Bird Keepers out there, chip in and help here !
I’ve re-read the post here, and suggest that you might get some Cuttlebone, which is a regular source of Calcium for them. Beyond that, if she doesn’t perk up soon, you should contact an Avian Vet, and get some professional advice.
Have a good Day !
