For this high capacity gravity feeder (not really an auto feeder as I said), I used a food grade five gallon bucket, a non-food grade lid (not necessary because it is underneath the chicken coop), a Little Giant Farm and Ag three gallon rubber feed pan, three 1″ bolts, six washers, and three lock nuts.
Using the centers of the bottom of the bucket and feed pan as a guide, I used a square to draw lines and marked spots about three inches out in a triangle shape. Above each of the main lines I used a hole saw to cut four holes through the side of the bucket. I drilled one hole in the bottom of the bucket and all three holes in the feed pan.
With them facing down, I placed the pan onto the bucket and inserted one of the bolts and washers to pivot on, then drilled the other two holes into the bucket when I was satisfied with the placement (may also try drilling a hole into the center of the bucket and pan for this purpose). I inserted the rest of the bolts and washers and put the lock nuts on.
The bucket cannot be tipped and I can carry it and the pan at once. It’s really nice only having to feed every 4 or 5 days while reducing food waste. If I end up moving it to open air I may build a post to hang it from and an enclosure to protect from rain.
