I think this is a pretty genius ideas, especially if you are tight on space and cannot use a 5 gallon pictures. I would suggest adding pictures of the process of putting everything together so someone else can mimic this set up.
For people new to keeping poultry, it may be helpful to include some pictures of how you assembled the feeder (if you have any available). Most everyone wants to save money, this is one way to keep costs down on raising chickens!
