I live here in va and my horses stay outside 24/7 365 days out of the year. They all have stalls....(2- 12x12x3 stalls shed row barns)(plus a 10 stall pole barn, which I store my tractors and implements in) and know where they are and can go in them any time they wish or into the run ins(12x20), but I never put them in there unless I am working on them or something. They are BLM Mustangs and 1 QH. They have been without shelter their whole lives before they came to me and the same goes for my gelding QH. He never was sheltered before I got him at 6. He was just left to run as an uncut gelding/a worthless stallion. So now they run here and there and everywhere they please. I have 25acres of fenced pasture turnout with running water from a cold water under ground spring and try to give them a natural type of horse life. I do not blanket them either. If the snow gets deep I go out with my snow blower and make paths for them and they are happy as pigs in****.
I can walk out and call them and any one that comes I can jump on and ride with or without a halter back in and the rest will follow and I have no troubles whatsoever in getting the one I want to ride sorted and singled out.
I can sort of understand about the show coat and all but why in the world would want to lock up your grazing animal in a stall/cell for X amount of hours a day? If I had an IR or Cushings horse I would use the dry lot/ sacrifice area, but not a stall.
How happy would you be living, sleeping, eating, defacating, urinating in the powder room bathroom?
