HI guys, I've noticed in a lot of photos where you keep your horse stabled overnight, outside of the UK you don't seem to build banks around the side of the stable. I was told that you have to build up the sides of a horses bed just incase he becomes cast. Now the thing is, I've never personally known this to happen to any of my horses or anyone elses at the yard where they are boarded. Is this because we 'bank' regardless, or is the 'cast' issue a myth? Would really like to hear people's thoughts on this.
