My neighbor had a horse get a leg stuck between the
rails that took hours to get out, fortunately no permanent damage. Another
neighbor's horse had broken pasterns due to pipe corral. One night my daughter's
mare apparently rolled too close to the pipe paddock (24' X 18') and injured her
back leg, probably had the leg stuck under the bottom rail, as the leg was
scraped up higher than the hock. Personally, I wouldn't want to confine
horses in small pipe enclosures UNLESS the pipe is covered with something. I see
lots of pipe paddocks with "no-climb" horse fencing attached to the
pipe panels. Much safer that way.
