The answer is no, but it does make our baked chicken juicier and more inviting. When baking, I usually tent my chicken (and other meat) with foil if I notice it's getting too brown before reaching the desired internal temperature. That's to prevent the skin from burning too quickly. Because the chicken skin is too thin, it cooks faster. Tenting the chicken with foil allows the chicken to cook well inside without burning the outside. Plus, it traps all the moisture and juice inside. Thus, the result is tender and moist baked chicken.
