I found this site after seeing their booth at the rodeo that has a feeder product that supposed to eliminates sand colic and choke by slowing down the feeding process and making the horse focus on eating.
Its keeps the horses head in the bucket, and in doing so the horses dont spill my exspensive feed for one and two will greatly reduce the risks of sand ingestion and choke which long term will greatly reduce the risk of sand colic.
I was specultive at first but after I tried it out on a few of my trouble bays and they just sat there for 36 mins with their heads in the bucket eating slower and not spilling any feed. I could'nt believe it, its going to change the way horses eat.
if you care about your horses health watch the vidoes.
