Leave the skin on, but score it with a knife... just a few shallow slices should do the trick. Skin is kinda tough, and it takes a little getting used to. Scoring it also exposes the meat so that it's a little more familiar and tempting.
I would leave the bones whole to encourage gnawing and scissoring the meat off. Having to work around the whole bones also reduces the likelihood of choking. Who knows, she might surprise you by at least eating the joint cartilage. I used to pre-smash the wing a little to encourage eating the bone (breaking the bone up inside the meat), but I now think it's better for them to figure it out for themselves. That said, if she
doesn't figure it out after a good dozen attempts, pre-smashing might be helpful.
good luck!
