Stormy's quantity's are good - follow them as a guide. I was inexperienced and made the mistake of switching slowly between kibble and raw and he used to be sick and runny. Just go cold turkey - excuse the pun. Just give raw, no more kibble. Chicken should be fine, though stick with wings for now as at her age she may struggle breaking up thicker bones. Introduce other meats slowly and one at a time, so if one upsets her, you know which one.
Don't forget tripe, liver, raw eggs, any organ, meaty bones (once old enough) for a good balance.
Good luck
