Really, to start it is easy. Chicken only for the first few weeks. Watch her poop and after a few days if it is runny, add more bone. If it is too hard, decrease bone. Don't worry if she doesn't poop the first day or only once or twice. Feed about 2% of their projected adult weight and if she doesn't eat it all, don't worry. Get a good digital scale and portion it out into freezer bags. Take the next day's food out and put it in the fridge at night so it will thaw by morning. I started with chicken leg quarters because they are bigger and they can't fit the whole thing in their mouth. If she is a gobbler, watch her closely and remove it when it is small enough to be a choking hazard. Backs are good but I stayed away from wings (too easy to choke on). Thighs are fine if they are large. I had to score the skin at first so that they could learn how to get through it. Some have more success just pulling the skin off and possibly feeding it later.
