BTW, I loved all the suggestions y'all had for horses that paw.  I will be using these for my little "brat".  However, any suggestions on feeders?  Preferrably something that can be constructed at home or from recycleables.

The only thing I can seem to whip up is filling an old tire with concrete and wiring a feed pan in it.  Or an inverted tire bolted to a flat concrete block.  Or half a plastic barrel w/concrete in the bottom, but gosh those are gonna be a pain to drag around.  "Brat" is in the pasture where I can't hang a feeder, though I'm sure he'd try to toss it if I could hang one.  Suggestions?

Place a flake/pat of hay down and pour his feed on the top.  He'll sling it around until he realizes he's losing it by acting badly.  This will also keep him very busy.

You could just put him on straight hay, he won't die without the grain.

I wonder if a shock collar could fix this behavior?

Maybe this will help.  I have a feeder I made myself using 3 old semi-truck tires.  I got them free from the used pile at a new tire place (the guy actually thanked me for taking them). 

If the air tube is still inside that is fine but you will have to cut off the valve stem as it could poke a horse in the face when they reach in for food.  Or you can just remove the tube completely.

Cut a piece of 1/2 or 3/4 in. plywood in a circle the same size as the tire.....this is to keep the feed off of the ground.  Place one tire on the ground, lay the plywood on top of it.  Stack the next two tires on top of that.  Take a drill and put a 1/2 inch or so hole in the plywood on opposite sides right next to the edge of the tire.  This is for you to run a plastic coated cable or a piece of chain completely around the 3 tires to keep them together.  One on each side it best.

Pull the cable or chain around the 3 tires and through the holes you drilled in the plywood as tight as you can and fasten it with a cable connector or a bolt.  I would suggest getting all the pieces together, the holes drilled and the cable or chain measured AND then assembling it out in the pasture.  It is hard to manuever this thing if you put it together in the barn and then try to move it.

Small tractor tires work also, but car and truck tires are too small (unless you are feeding mini's).  This feeder works best for hay but you could put a feed pan in the bottom too. 

Good luck !

We use these no tip feeders in our TB pasture. It took a while to figure out what kind of system to use with them since they pretty much would try to destroy their feed buckets or the over the fence kind of feeders.  We have used these with very good results for the last year.
