I can’t believe that no one guessed the Mystery Photo from last week.
I thought for sure that my clue that we use it every day on our farm would have helped. But I guess not. OK – here was the picture from last week 
and this is what the item is.
It’s used to force air into our chicken coop to keep the air inside not only cooler, but it also helps to recirculate it. The top part uses the wind to move the bottom part so it is lined up with the wind and that’s where you get the wind blowing down the chute into the coop. Kind of an early fan for your chickens.
