Our sheep and goats have access to our main barn with nearby frost-free waterers, we just like to feed them out in the pasture so that they get extra exercise going back and forth.  The sheep tend to be hardier in that they don’t mind being outside as much as the goats, but the goats are happy to spend time away from the barn on sunnier days, even if it’s chilly out. Each section of pasture has three-sided shelters and frost-free waterers so that there are areas where they can stay dry, get out of the wind, and stay hydrated when and if they need it.
