It’s going to be a year or so before I can build a barn. My horses are starting to run each other off feed buckets. I’ve seen where you can make “feed stalls” out of panels. I definitely want something temporary. Any suggestions on how to do it? 

When I first got my land, I set up a 'hitching post' station.  Set two posts and nailed a 2x6 across.  Then fastened a bucket on each end.  I usually tied them up to eat, then got to where I just tied up the mean one.  Turned them loose when they got done eating.  The board across kept the mean one from rotating around and around and kicking at the other.  All my 'things' were in the front part of my trailer.

Then I got two more horses...  another hitching post... before I got a barn.  It was real easy to put up in a couple of hours.
