Thank you for your suggestions.This helps alot. I have a very large unused shed on my property and I think I will prop the doors open and install a high roosting bar and see what happens. I may make a trail of meal worms to entice them in.This is normal. My turkeys roost outside in all kinds of weather in an area sheltered from the prevailing wind. Fortunately we don't get ice storms here.
You do not need a fully enclosed coop unless you need it for predator protection. A three sided lean-to with the open side facing away from the prevailing wind can work well as long as it is tall with the roosts far enough away from the sides and roof to allow the turkeys to be comfortable on the roosts. The taller the structure is, the better.
I do not rely on treats for responses from my turkeys. When I want them to go somewhere, I herd them where I want them to go. If where you want them to go is not where they want to go, it can be helpful to put something up to block their possible escape path whether that block is a temporary or permanent thing.
