Ended up using 2 garbage cans from ace with the bottoms cut out bolted together
He had to cut 21 metal triangle pieces for the top and then used roofing caulk to cover the seems
I do not know how it worked out, kind of a fly by pants idea to make a silo on the cheaper end of the scale
probably needed some modification after the fact
All you need now is a solid roof on the outdoor run, which is of a perfect height in my opinion, especially if you are keeping any of the rare cultural treasure breeds.
