Turkeys don't seem to get any smarter with age either, at least not mine anyway. Sometimes we find that we need to 'lock them up' for various reasons (they are free ranged entirely). Company coming over is our major reason. They don't behave well with certain people. We put them in the fenced area with the geese. A 7 foot fence with no netting on top. They stay in there all day but when it is roost time they fly out and go roost. They can get out all day but don't. For dumb. But hey, it works perfectly for me!
That is turkeys!
Mine are overly friendly with guests. They want to be the center of attention. I can never figure if they are truly stupid or cunning like a fox, they always seem to get what they want.
