This makes a great freeze ahead meal. Place chicken in 2-gallon freezer bag along with seasonings, green chilies, corn, and beans. Seal bag well and freeze. The night before you are going to cook it, take it out of the freezer and put it in the fridge to thaw. In the morning, dump contents from freezer bag into your slow cooker. Add 3 to 4 cups of chicken stock. Cover and cook on low for 6 to 8 hours.
