Prepare the Seasoning - In a large bowl, combine olive oil, salt, Italian seasoning, paprika, garlic powder, onion powder, and black pepper.
Season the Surface - Dry the chicken thoroughly with a paper towel, then add them to the seasoning mix. Turn to coat evenly.
Cook the Chicken - Add chicken stock to a 6-quart slow cooker. Add the seasoned pieces in a single layer. Cover and cook on the "Low" setting for 1 ½ to 2 ½ hours until the internal temperature reaches 160 to 165ºF (71 to 74ºC). An 8-ounce breast takes about 2 hours.
Shred the Chicken - Shredding can be done directly in the crockpot, or transferred to a cutting board or plate. Use two forks to shred into desired-sized pieces. Remove the chicken from the crockpot if not shredding immediately to prevent overcooking.
Serve - Use shredded chicken immediately or store it in the refrigerator until ready to use.
