its this english american language thing again! if by stall you mean something that they can only stand in, and not turn around, then i think that is cruel, apart from behavioral and emotional issues, it could have health affects too. so yes, i think that is wrong. if it is what we call a " box" in the uk , about 12'x12', then that is still not ideal,imo, but infinately better than a stall. mine are out 24/7 with unlimited access to stables, so they can wander in and out, and i think all horses should have the freedom to just be a horse, and interact with other horses, for at least several hours a day.
