Place the corn on a half sheet tray and bake for 20 minutes. Remove and cool slightly, then shuck the corn and remove the silk. Place a small bowl upside-down inside of a larger bowl. Rest the tip of one ear of corn on the smaller bowl and cut the kernels from the cob, which will fall into the larger bowl, and then repeat for the remaining ears of corn.
Place half of the kernels in a blender and blend on high speed until smooth. Add the pureed corn and whole kernels to a medium pot set over medium heat, then add the cream and butter, and bring to a simmer. Cook, stirring occasionally, until reduced to a pudding-like consistency, about 7 minutes. Finish with the chopped chives and add salt and pepper to taste.
Place the kale in a bowl and coat with 1 tablespoon of the olive oil. Lay out the kale in a single layer on a full sheet tray, then sprinkle with salt and bake until crispy, 10 minutes. Cool the kale completely.
Preheat the oven to 450 degrees F.
Using a pair of kitchen sheers, remove the backbone of the chicken and break down into 4 pieces.
Using either a mortor and pestle or a spice grinder, process the fennel and peppercorns to a coarse powder. Rub the chicken with 2 tablespoons of the olive oil and sprinkle liberally with the spice mix and some salt.
Coat a 12-inch ovenproof saute pan with the remaining 1 tablespoon olive oil and heat over medium-high heat, just until the oil reaches its smoke point. Place the chicken skin-side down in the pan. Place the thyme on and around the chicken in the pan, and then place the foil-wrapped brick on the chicken. Reduce the heat to medium and cook for 5 minutes, then transfer the pan to the oven and cook for 30 minutes.
Carefully remove the chicken from the pan and place on a cutting board skin-side up. Drain the fat and the thyme from the pan and set over high heat. Add the chicken stock and the honey, and cook until reduced to a thick glaze, scraping up all of the browned bits from the bottom of the pan. Brush the glaze on the chicken and finish with some flaky sea salt and freshly cracked black pepper. Serve the chicken with the creamed corn and crispy kale.
