01 - Place chicken breasts in the bottom of the slow cooker in a single, even layer.
02 - In a medium bowl, whisk together the barbecue sauce, honey, Worcestershire sauce, garlic powder, onion powder, smoked paprika, and black pepper until smooth and well combined.
03 - Pour the sauce mixture evenly over the chicken breasts, ensuring all pieces are covered.
04 - Cover and cook on low heat for 4 to 5 hours or on high heat for 2 to 3 hours, until the chicken is tender and reaches an internal temperature of 165°F.
05 - Transfer the cooked chicken to a cutting board and shred using two forks. Return the shredded chicken to the slow cooker and stir thoroughly to coat with the sauce. Serve hot, garnished with fresh chopped parsley if desired.
