Hey we had a verry energic horse who had a leg injury, we always had a lot of toys in his stable, music and we had hay in a net so he played with that. Brushing helped to with my horse. I hope your horse will get better soon!
My horse is also on box rest and in the first week kicked his back wall out we have since given him lots of toys like swede on string and treat balls etc and we spread his hay in multiple different nets around the stable to keep him thinking. We also adjusted his feed for less energy and
Hi, Make sure you aren't giving your horse any feeds with lots of energy, this also includes fatning feeds, they seem to have a lot of sugar witch has a lot of energy, if feeding a a weight gain I would suggest full fat soy bean meal
Hope this helps :)
