Start by rinsing the chicken breasts under cold water and patting them dry with a paper towel.
In a small bowl, mix together garlic powder, onion powder, paprika, dried thyme, salt, and black pepper.
Rub the olive oil over the chicken breasts, then coat them evenly with the spice mixture.
Place the seasoned chicken breasts in the crockpot and pour the chicken broth over them.
Cover the crockpot with the lid and set it to cook on low for 6 hours.
After cooking, check the internal temperature of the chicken to ensure it has reached 165°F (75°C).
When done, use two forks to shred the chicken inside the crockpot, mixing it with the broth for added flavor.
