Place chicken in a large zip-top bag or bowl; pour pickle juice over. Refrigerate at least 4 hours or overnight, turning occasionally.
Remove chicken; pat dry with paper towels. Whisk eggs and milk in a shallow dish.
Combine flour, paprika, garlic powder, onion powder, salt, and pepper in another shallow dish.
Heat 1 inch oil in a large skillet over medium-high to 350°F.
Dip chicken in egg, then dredge thoroughly in flour, pressing to adhere.
Fry in batches 3-4 minutes per side until golden brown and cooked through to 165°F internally.
Drain on paper towels; serve hot with preferred dipping sauce.
