Bmustee,
I am faced with a similar situation as you that my finch broke a leg last week. Today it appears the toe may be dying. I have her going in this afternoon to the vet and taking your post
Can you e-mail me any photos of accessibility things you have done in the finches cage or aviary. I have some ideas as a friend has handicapped birds but would like to see what you've devised.
I know this is not a finch board, so you may personally e-mail me at: jezazoo@yahoo.com
Many thanks.
