Ok I just want to settle a debate.... If you put 8 chicken breasts in the oven, will just a single chicken breast cook within the exact same timeline? Does quantity affect cooking time at all?

Not really. Just make sure you seperate them before you put them in. Chicken breasts stacked together ontop of each other like pancakes would be extremely hard to cook. I make cornish game hens in the oven that taste great and they all turn out done at the same time.
