Dear XXXXXX:
Thank-you for your question. I am sorry to hear about your finch's problem.
To start, could you please (if you haven't already) put her in a seperate cage from the budgie. Crank the room temperature up to 80 degrees F (27 C), and increase the humidity; these things shold help her a lot. Make sure that her food and water are close so she doesn't need to move much to get them.
It was good to NOT use neosporin again: the ingredients will not help her, and because it is an oil-based ointment it could actually make her feel worse by messing up her feathers and interfering with temperature regulation.
She needs to see a vet, whether ithe leg is broken or not, because the way she is acting says that she is in pain. Here is a link to help you find one: www.aav.org/vet-lookup. A vet can prescribe pain medication and antibiotics for infection.
I wish you the best; my Goulies lived until they were in their twenties!
