I was off today and took some pictures of the stall that Duncan (horse) shares with the chickens that live in the barn. This is a 12X12 foot stall.
In this first picture, you will see Duncan's feed box with a hay rack over-top. I mounted two baskets (no longer used in the house)under his feedbox, which the hen's use as nests. This past summer, one of the Wheaten Ameracauna's brooded 6 eggs in the top next box with horses, goats, ducks and geese all watching. You will note, that I mounted a piece of plywood from the ceiling to the top of the hay rack, to discourage the chickens from roosting on his hay rack, which meant their droppings went into the feed box.
Here you can see the roosts mounted on the wall (5 ft. off the ground), In the corner is a built in feeder. I had to do something to keep Chantilly, my beautiful Belgian from getting to the chicken feed. Some of the chickens opted to model the roost and its effectiveness.

Basically, I mounted a piece of plywood as a shelf, then mounted 4 2X4 cust on 45 degree both ends into the corner of the stall. Leaving a couple of inches from the shelf to the bottom of the first board. I then mounted another 2X4 about 2 inches in front, thus making a trench where the feed falls out. The chickens can eat for a week or more, while Chantilly looks on, but can not get to the feed. I win!!!!
edited to add that this is a 12X12 foot stall.
