My son says this is the first and last box he will make! It did take longer than expected. Its 2x3x15"h. We made it out of the recycled plastic/wood composite decking material because have been known to chew wood. I attached the hay bag in the center as I did on the mats.
There is a local guy who makes horse hay boxes and he is going to down size one for the donkeys. Pics when I get it.
