I wouldn’t be terribly concerned, but I would be tempted to have the vet out anyway. I wouldn’t classify this as “normal” behavior, although it could be normal for this horse. Is it worse during the summer or winter? Does the horse get plenty of turnout?
I would make sure the horse is fed hay only on the ground and grain fed on the ground if possible as well. Lots of turnout time, and maybe adding flax and msm to the diet.
