Can't see his head and feet clearly, but if the feet are a bright orange then it's a guinea. I can't see enough here to make a good guess, I can't even see it's snood.
I really want to see the pictures on this one.
Do you know 100% these are all tukeys and have you raised turkeys before?
I only ask because a little voice in my head is saying that you might have a guinea among the mix.
