Place the chicken into the pot of a slow cooker and rub the seasoning mix all over the skin and inside the cavity of the chicken. Stuff the lemon halves into the cavity, then pour broth around the chicken.
Following manufacturer’s instructions, set to cook on high for 4 hours, or on low for 6 hours, or until chicken reaches an internal temperature of 165°F.
Place oven rack in the center of the oven; turn on the broiler.
Transfer chicken to a shallow baking dish or rimmed baking sheet and broil until the skin is golden brown and crisp, about 5 to 10 minutes. Serve warm.
