I was at D&B the other day and a U of fence panels with a arched roof caught my eye. The roof was called a corral shelter and covered a 12 x 12 space, they were storing pellet stove fuel in it.  The price seemed reasonable and I had seven unused regular panels and a gate panel and got the idea to build a 24 x 24 feeding and shelter area.  I purchased two corral shelters and an extra panel to divided the area into two 12 x 12 feeding areas.
I assembled the first shelter frame in place on top of the supporting panels spending a lot of time standing on a ladder,  it took me about three hours and was sort of a pain. To build the second one, I contacted Terry MacDonald who came over and we had the second one build and placed on top of the fence in a bit over an hour. As only one frame could sit on top of the center fence panel, the other one had to be bolted to the first with some spacers, this approach seems to be working quite well.  I needed enough space between the two shelters for the covers.
Side panels are available, but sort of $$ so for this winter I used 12 x 10 plastic tarps.I have about 8 hours total in putting it together, and hope my stock will enjoy using it when it is raining or snowing this fall/winter. // Rob Adams
