I don't like to keep the feeder and waterer in my Little Monitor Coop, which is only 4'x4'. They take up valuable space, are awkward to fill, and are prone to be knocked over when the chickens are pushing and shoving to get to them. Since the current run is unroofed, being 100 feet of electric poultry netting, I had to have a shelter to get them outside where they would be easier for me to get to and safe from being dumped.
This shelter was made from salvaged wood and scraps of metal siding that we found on the property.
Based on the dimensions of the materials available, it ended up 46" wide by 34" deep,* with the front legs 36" tall and the back legs 29" tall. No plans, but I took a lot of photos while DH was building it:
The roof frame, with two crossbars to provide support for hooks. I hang the feeder and put the waterer up on blocks, but I could hang a gravity waterer or vertical nipple waterer if I wanted to (horizontal nipple waterers work better sitting on a stable surface). Or, I could hang a second feeder if I had a larger flock.
You can see in this photo that the legs were trimmed at an approximately 10-degree angle to make them nicely flush with the roof slope. Then we connected the legs with boards on the sides and back. Since we were using heavy pieces of salvaged lumber we didn't need to add diagonal bracing to keep it stable. A lighter structure should have diagonal bracing to prevent racking.
The scrap siding was secured to the roof frame with screws and washers designed for the purpose, bent down to provide better shelter from horizontally-blown rain, then fastened securely. Because we didn't have another piece of metal, a random piece of scrap shingle did the job on the back. We were prepared to add additional shingles if the feed got wet from blowing rain but it wasn't necessary. This shelter has been through Hurricane Zeta and a very wet and stormy winter -- keeping the feed perfectly dry. Your winds may vary.
The final result is 100% chicken approved!
*I realized after measuring it, that this structure is actually larger than the coop section of some prefab coop-and-run combo units and checked the square footage. At 11.5 square feet it would make a nice broody hutch or a quarantine coop -- just add walls.
