In a large bowl, combine the chicken cubes, dill pickle juice, ranch seasoning, olive oil, garlic powder, onion powder, black pepper, and salt. Mix well to ensure the chicken is evenly coated.
Cover the bowl and refrigerate for at least 1 hour, or up to 4 hours for more flavor.
Preheat your grill to medium-high heat. If using wooden skewers, soak them in water for 30 minutes to prevent burning.
Thread the marinated chicken onto the skewers, leaving a little space between each piece for even cooking.
Place the skewers on the grill and cook for 10-12 minutes, turning occasionally, until the chicken is cooked through and has nice grill marks. The internal temperature should reach 165°F.
Remove the skewers from the grill and let them rest for a few minutes before serving. Enjoy them warm!
