Materials: fruit jar feeder base [I like the metal ones] PVC 2" x 4" adaptor 2' - 3 ' length PVC pipe, 'test' lid 6" pipe clamp if needed aluminum pie tin paver I didn't use any glue. The pipe can be as long as the height of your coop [and your height ] allows. I fastened the feeder into the corner with the pipe clamp. I set the base on a paver to keep it level. I drilled a hole in the lid, threaded a rope through it and tied a knot, ran the rope thru' the crate roof and fastened it so that I can check the feed level from outside the crate.
