I don't remember if they can or not, but I don't. Buy some unmedicated, trust me, they'll use up the 50lb bag without a problem. I don't do anything special for mine. Treat them just like chickens here, except if incubating, raise humidity to rainforest levels during hatch.
If doing BB turkeys, spend the least amount of time with them possible or you'll end up with pets. Get those hamster water bottles for them to drink from. They are sensitive and it seems like looking at them wrong can kill them. Don't free-range until they're bigger, I lost some that way (fully feathered), and it halved my flock size (predator). Keep a heat lamp on them for longer than you think is necessary. My big girl is 20lbs+ of muscle, but she still gets cold very easily.
