That's quite a story! Poor little thing I'm so glad you've taken her on & given her a good home.
It might seem like small changes to you but must seem like massive changes to her, plenty to markedly change her behaviour in such a short time I'm sure, she's no longer starving, she can exercise properly & that alone is enough to make her sleep well I would think!
Being short of decent food & in a very small unsuitable cage would probably be enough to make any ham bite so it's no wonder she seems calmer & more at ease with you.
Hope she continues to improve even more & that the other ham finds an equally good home too.
