I purchased a yearling ND doe from a lady on August 31. All her goats were penned together with her buck, so she said she was possibly bred, but obviously had no idea when she would be due. Turns out she is pregnant, she started developing an udder around November 18. Anyway, I'm in northern MN, so we're heading into the coldest part of winter. I do have the goats in a barn, but it's not completely closed, the big door on one end stays open to let the horse in for water. We provided the doe with a covered plywood box about 30" high by about 3'x4', she sleeps in it, but I'm wondering what to do for the kids when they arrive. Our average January night time temps are -8F, but it often gets to -20 or colder. I'm planning to make one of those plastic barrel warmers, but will that be enough? I'm also going to make a couple kid coats out of an old wool sweater. Any advice?
