I had a situation like yours. I ended up having to seperate them since my littlest didn't get a chance to eat or anything. My oldest tort would pick on her constantly. We ended up giving her to a friend who is actually on this site! We didn't have the room for two pens. She was a life saver and my little tort is doing much better now that she is in better hands and not being picked on all the time. Good luck with yours. You might want to wait until Padme is bigger so she can hold her own with the other one.
