Hi and welcome to EBN.
1. I would give her bone. In what shape and form, I don't know what is available for you. I use to give my pup ground bone as part of the meal and some bigger bones to chew. If not ground they should be as big so she can't choke on them. I don't give any oats or any grains. In the beginning chicken and turkey are great, they digest easily. Chickens life span is so short, that in my and many others opinion, their bones have hardly any calcium, so you need introduce other source as well.
2. As food and nutrient source it is not enough to give big bones to chew.
3. I would not give any pig ears. My pup almost choked on one. He's tongue was already blue by the time I fished it out from his throat, VERY scary.
