Different Poults, Different Strokes.
Turkeys, like most creatures, can each have their very own and distinct personality.So in that sense it makes your question a bit of a challenge to answer.
A little more information would also be helpful in giving a more descriptive answer.
How many turkeys do you have? What kind? Are they kept with chickens in the same flock? What type of coop do you have for them?
Generally speaking and from my experience if one turkey goes in, usually they all will, but if not, they're all roosting on top of the coop. Or if the alpha isn't the one that doesn't go in, but another one does, you may have some both in and out. Naturally turkeys would rather be outside, unless the coop is very large. Also, routine is critical with any bird. If you can be very consistent about encouraging or corraling them inside the coop every night, sooner or later, they will get it and understand that where they wake up every morning is where they need to be when it gets dark and they go to sleep. But you must be consistent every single night, not missing a night, and it can or cannot take quite awhile for them to catch on.
