Place the chicken pieces in the bottom of the slow cooker.
Whisk the barbecue sauce and sugar together in a small bowl until the grains dissolve.
Drench the meat in the sweet glaze so it is fully covered.
Cook the chicken until it is tender enough to fall apart easily.
Break the meat into shreds and toss it back into the warm liquid until every piece is coated.
Adding a tiny splash of apple cider vinegar helps balance out the sweetness of the sauce.
