Im sorry, but they will if you dont molly coddle them, its just that they aint used to it, tip; removed all your dried food, stick a raw chicken leg in with them, they will eat when hungary
if we shut you in a room, with nothing but raw meat, you would at some time, rather than die of hunger, eat the meat, a ferret is no different

1, ferrets have a very short digestive track and I would see starving them for a long period of time wrong, to get my ferrets to eat meat they would proberly have to go a very very long time without food.
