Thanks everyone, that info was really good.  I've heard of chicken frames being good but do you think I could give her a whole one as she is very little and seems to have a fairly small appetite.  Do brisket bones look really fatty too?  i think I asked the butcher for some a few months ago and it looked like one half of the photo was covered in a white fatty skin?? meat?? I didn't end up giving it to her.
