Baby turkeys are the stupidest bird that ever was hatched. They will starve to death surrounded by food because they don't know that they are supposed to eat it. In the wild, the momma turkey will call them to their food and teach them how to eat. In big turkey facilities, they dye the food to make it look weird to encourage them to peck it.
If you don't have a momma turkey, then you can put a baby chick in with them to teach them what to do. Baby chickens are born knowing that they are supposed to eat and drink, so the turkeys will copy. Or you can dip their beaks in the water a few times and put something shiny near the food and water to encourage them to peck it.
I also get better luck when I keep the baby turkeys away from real dirt for the first month or two, especially the Red Bourbons. I can let the momma chickens and ducks take their brand new babies out on the dirt or use local sandy soil in the brooder box for the chickens, but the survival rate goes down for turkeys when I try this. (Don't know why.)
Turkeys are very stupid. If you bring them outside when they are several months old, the first thing that they will do is try to fly into a container of water or fly over a fence and forget how to fly back. Turn your back on them for a minute and they will find a way to commit suicide. It's best to treat them as special needs birds. I would never accuse a chicken of being smart, until they are measured against a turkey.
