I buy a lot of whole chickens, too. The biggest birds I find from industrial farms (like Perdue) hover around 5lb max. The birds from smaller farms hover around 3lb, basically what you see. I do see some chicken leg quarters and split breasts that seem to be suspiciously large, but not nearly twice as large as the Perdue 5 pounders! The big birds might just get sold to fast food/fast casual restaurants and not to regular joes like us. I also think it is possible that they buy enough more chickens than we do to weigh any averages towards them as well.
