Turkeys don't stink, but their coop might get smelly if it's not well-taken care of. If you are used to taking care of chickens, it's about the same thing except they are bigger. You might visit the man up the road with your dad and see how he keeps them.
But I think the biggest concern with you getting turkeys is ... do you have the time to take care of them? do you have money to buy feed for them? do you have the a coop, and enough space for the turkeys?
If your answer is no to any of the above, get someone to advise you, or you could join a 4-H group or a poultry club in your area.
