We have recently acquired a couple of bottle-fed ewes. They are about a week and a half old now. We originally got them at 4 days. They are so sweet and lots of fun too. However, they are currently living in my dining room. Which is sweet and convenient but a little messy and a little stinky. I'm wondering when I can move them out to the barn? I'm in Vermont and while it's been way warmer than usual, it still gets quite cold at night. I don't have electricity out at the barn so I wouldn't be able to use a heat lamp on them. Any advice would be helpful.
