Well, I have a few options for enclosed foaling area, although none would be "warm", just under cover. Move in with Baybe and Tilly, and fence off a corner of their shelter. dig the snow out of her shelter, and figure out a way to block the wind from blowing in. Move over to one of the shelters at the gelding pen, but I'd have to figure out a way to separate all the boys for meals. Move her into the foaling stall in the mare barn (I have two stalls with a removable divider, so would have to figure where to feed two mares).
