I'm by no means a turkey expert but I do get to watch them daily for the last 20 years or so since they moved into the area.
Here are some observations I've had...
They seem to have a winter flock (and range) and a rest-of-the-year flock and range. And these areas can overlap. I must live in an overlap area. We have large wintertime flocks that have numbered as high as 103 birds three winters ago. That year, and most years, The wintertime flock is well established. They usually hang together tightly. "X" number of birds yesterday, the same number (and the same individuals) today and the same number tomorrow. This winter was slightly different, though. Instead of 1 large group, they were in smaller flocks of up to 30 each and they would interact with other flocks during the day. But eventually, the flocks would separate and go their own way.
Usually around now each year, the winter flock will break up and somewhat disperse. There will still be plenty of "resident" turkeys that remain but a lot of them seem to go elsewhere. But the ones that remain stay here. They don't range very far like some of the earlier posters have said. They are here and they stay here. They roost in the same trees every night. I watch them fly down to the same places from the same trees, have the same daytime patterns and eventually fly up to the same trees from the same "take-off zone" every evening. They are extremely predictable.
The resident males also hang out in somewhat established groups but they will split up a bit during mating time. A few years ago we had a group of 4 long beards that were inseparable. They were always together. I could identify them fairly well. One of them had a trait that his head was alway blue-ish in color. it didn't change colors when it got excited like "normal" gobblers heads do.
Those 4 gobblers tolerated each other quite well. Very little fighting, ever. But if another group of "strangers" were to show-up, it was like a turf war. It was on!
Jakes also hang out in gangs during the mating period and they will harass smaller groups of adult gobblers. I've watched a dozen or more jakes squabbling and bickering among themselves until a couple long beards show up, then the younger birds turn on the old men.
Sometimes it's hard to tell if gobblers hate each other or love each other. I've watched them rough-house playing a lot.
One of the more humorous things we see sometimes is a group of 3 or 4 gobblers chasing each other around hickory trees in my yard. Round and round they go. Non-stop for minutes at a time. It's hard to tell which one is 1st and which one is last. Then they peel off and run circles around another hickory. I reminds me of The Keystone Cops or 3 Stooges. It's hilarious.
Groups of gobblers are not afraid of foxes. Many times, I've watched a fox appear near a mixed flock and the gobblers would split off and "escort" the fox out of the area.
Mating is brutal. There are times that it looks like the gobbler might kill the poor hen. After he gets off her, she may lay there for a minute and I wonder if she's dead, but she always gets herself together, gets up and walks off.
Masturbation is very common among gobblers of all ages. If you ever watch a gobbler kind-of hunched-up with tail low and wings fluttering a bit, he is in the act of "it".
As far as nesting sites goes, I've seen them nest just about anywhere from more open woods to hayfields to transitional cover.
Hens do not like to expose poults when they are very young. We have tons of turkeys here, but I seldom see the babies until they get a little older.
And the early age that poults can fly well enough to get up into trees is amazing. They are extremely young when they can begin to fly.
