Combine the sugar, vinegar, pickling spices, bay leaf, 1/4 cup salt and 2 cups cold water in a large pot and bring to a boil, stirring, until the salt and sugar dissolve. Fill a large bowl halfway with ice. Remove the brine from the heat and pour it over the ice to cool to room temperature. Add the chicken skin-side down, being sure to keep the chicken submerged. If the chicken is not completely covered in brine, add more cold water. Cover the pot and let sit for at least 1 hour at room temperature or refrigerate up to overnight.
When you're ready to fry the chicken, pour enough oil into a large Dutch oven to reach about a third of the way up the side and deep enough to submerge the chicken. Heat the oil to 350 degrees F. Preheat the oven to 200 degrees F and line 2 rimmed baking sheets with wire racks.
Remove the chicken from the brine and place in a large bowl with the buttermilk. Put the flour in a large paper bag. Season the flour with the dill, pepper, garlic powder, onion powder, paprika and remaining tablespoon salt. A few pieces at a time, transfer the chicken to the bag with the flour and shake well to coat. Place the coated chicken on the wire rack-lined cookie sheet.
Fry the chicken in batches until golden brown and the internal temperature measures 165 degrees F, 5 to 6 minutes per side. Remove to another wire rack-lined baking sheet and transfer to the oven while you cook the rest of the chicken. Let cool slightly before serving with the Hot Honey Sauce.
Hot Honey Sauce:
Stir together the honey, butter, hot sauce, paprika and cayenne in a small saucepot over medium heat. Heat and stir until smooth and all ingredients are combined.
