Bought from a shepherd who built  it on a skidoo trailer, it has been since reinforced with welded metal bars.
It needs to be stored inside as the box is made of painted wood (plywood).   It  has a hinged wooden partition on the inside and can carry at least
 7 ewes and 4 lambs. The inside measurements are 7'4" X 3'6" X 3'9". Asking price is $300.00. Posted on behalf of Arn Snyder.  Please contact him at [email protected] if you are interested.
