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.
