Like this one DHW?
That's awesome, but that won't work as well in that space. Here's another picture of it.
It's at a boarding facility, so I can't make any major renovations, and I'll need to leave it how I found it.
@joe yeah the hay bag would work, and I have a couple, but I'd like to do free choice hay and they just don't hold enough. Plus I hate loading hay bags. They're a pain in the butt.
I also value the no waste design of the grazer box type, whereas a vertical one (like the corner wall) looks like it would spill hay onto the ground, what do you guys think?
You guys gave me an idea though, since I can't have a frame on hinges because of that plastic feeder, I could build a 3 sided frame, leave the whole front open, like a big slot, and I can slide the grate into that slot, and then let it drop down. When I have to refill, I will just lift the grate up, slide it out the slot, and refill with hay. I don't think a horse could lift it up, get it caught in the slot, and pull it out. Thoughts?
