Place the chicken inside the slow cooker along with the chicken broth. Sprinkle the taco seasoning and ranch dressing mix over the chicken.
Cover and cook on low for 4 to 6 hours until the chicken is fully cooked.
Remove the chicken and shred with two forks. Stain juices in crock pot so only clear juices remain. Add the chicken back in and serve as you would for tacos. Serves 8.
