Heat the olive oil in a large skillet over medium heat.
Brown the chicken thighs for about 3-4 minutes on each side, until golden brown.
Transfer the chicken to a slow cooker.
Add lime juice, garlic, cumin, paprika, cinnamon, salt, and black pepper.
Pour the chicken broth into the slow cooker.
Make sure the chicken is fully covered by the liquid and seasonings.
Cover and cook on low for 3-4 hours or until the chicken is tender and easy to shred.
Do not overcook, as this can make the chicken tough.
Remove the chicken from the slow cooker.
Shred the chicken using two forks, and then return it to the cooker to soak up the juices.
