Place the chicken breasts in the Crockpot.
In a bowl, mix BBQ sauce, brown sugar, apple cider vinegar, Worcestershire sauce, garlic powder, onion powder, smoked paprika, salt, and pepper.
Pour the sauce over the chicken and cover the Crockpot.
Cook on low for 6-7 hours or high for 3-4 hours until the chicken is tender and easily shredded.
Shred the chicken using two forks and mix well with the sauce.
Serve on buns, tacos, or over rice for a delicious meal!
