Our Aspen is going to be a mama!! We are extremely nervous that its winter, shes a 1st time mom and we have no experience with this. She usually sleeps in the sheep shed, but we want to encourage her to give birth on our front deck. We are building her a house/whelping box where we can keep an eye on everyone (and provide a heated dog bed). Any suggestions on getting her to choose our location. And if she insists on staying near the sheep (further from our house), how do we keep them warm and safe from the sheep? (We are in high 20s at night). Any help would be wonderfully appreciated.
