We went through a lot of different ideas for our hay rack. We wanted something to hold a lot of hay for the piggies, as they really like it, but we also wanted something to hold it up a bit, and yet be safe. We aren't sure of the age of our two piggies, but they are small. DH bent this grid and lined it with chicken wire. We checked very carefully to make sure there weren't any sharp points poking out, and unwound a few loose wires to make it extra safe. We also added coroplast to the open side to keep the piggies out of the hay rack.
