Yes, raw chicken is correct. I have made chicken jerky for my girls several times in a dehydrator and the oven. The most important thing is that you make sure you slice the chicken as thin and uniform as possible (a little on the frozen side helps). If the pieces are not the same thickness, the dehydrating time varies too much. You will have some that get over crisp while other parts may not be dehydrated enough. My girls prefer chewy rather than crispy. In the dehydrator I use plain chicken breast with no added oil or seasonings. In the oven, I coat the pieces with a little oil.
