Special equipment: Grill, 4 bricks wrapped in foil or a heavy cast-iron skillet, food processor or blender, instant-read meat thermometer
Remove the backbone from one of the chickens. Split the breast plate and press down on the chicken in all joints to flatten it. Tuck the wings under so that the chicken lies flat. This will help it cook evenly. Repeat with the second chicken.
In a small bowl, combine the chile powders, paprika, fennel, garlic powder, onion powder, oregano, sugar, salt, and pepper. Mix well, then rub the mixture all over the flattened chickens, making sure you get it into all the gaps in and around the joints. Marinate the chickens in the refrigerator for 1 hour uncovered. (Leaving the chicken uncovered helps the crust dry out and ensures you get a nice crispy skin when it cooks.)
Heat a grill to medium heat and rub down the grates with a lightly oiled paper towel to clean it and create a nonstick surface. Place the chickens skin side down on the grill. Watch for flare-ups when the chicken initially hits the grill, as the fat will render and drip down. If necessary, move the chicken to a new spot out of the flames. This will occur only in the initial drop. Place foil-wrapped bricks on top of the chickens to flatten them as they cook.
Cook for 15 minutes, then remove the bricks and flip the chicken. Cook for 18 to 20 minutes or until the internal temperature between the leg and thigh joint reaches 165 degrees F on an instant-read thermometer.
Transfer the chickens to a cutting board and let rest for 5 minutes before slicing each one into 10 pieces. Serve with apricot-mint chimichurri.
Place the apricots and honey in a glass bowl; cover with hot water and soak for 10 minutes.
Meanwhile, in salted, boiling water, blanch the mint, parsley, and cilantro for about 30 seconds. Shock immediately in ice water and spread on a paper towel-lined sheet to dry.
Remove the apricots from the hot water and roughly chop. In a food processor or blender, combine all ingredients except the olive oil and process until all ingredients are finely chopped. With the motor running, slowly incorporate the olive oil and pulse until just combined (the consistency should be like a thick sauce). Cover and store in the refrigerator to meld, about 10 minutes.
Prep-Ahead Tip: Split, flatten, rub, and refrigerate the chickens a day or two in advance of the party (or pop them in a cooler if heading off on a different outdoor adventure). The longer they marinate in the dry rub, the better the flavor, and it makes for easy grilling when it's time for the backyard bash to start. Prep-Ahead Tip: Make chimichurri one day ahead and press plastic wrap on surface, to
