remember seeing these pictures in your history book back in school? think about this logically. how would you even be able to feed and water all of them during the multi months journey, not only logistics, but even distributing the food and water. and assuming you did, they are chained in place, packed as tight as possible as cargo. they would feces shit and piss themselves. the entire "stock" would have gone contagious and septic in a few days, and by the time you arrived at port the entire "merchandise", would have already died of sepsis.
