Keep it simple. Best way to approach winter. And intervene when horses can't figure out simple.
Heavy snowfall warning? Hibernate. Blizzard? Hibernate. Frozen water trough? Put hibernate on hold. Use profanity. Show horses that they don't need to Dessicate whilst doing the Hibernate. Trudge across 200m of two deep feet of snow, dragging Welsh pony Drama Queen and her court to the other heated water source. Swear when Her Pony-ness decides she is just NOT sharing a water trough with a bunch of minis. Re-drag Her Highness to new water source AGAIN. Then, perform the stupid human trick for a THIRD (and last) time. Strip off Pony Tiara and lock horses in with new water source - that is, pony gasp, beside the un-cool minis. Hibernate.
