Ok, 3 weeks ago tomorrow a pygmy doe we adopted had twins. This was our first kidding, and our barn is not heated, nor does it have electricity. And we live in Upstate NY and it was just frigid that night (and most nights since) So being the worry wort that I am, I brought them in the house and they have been bottle fed since. My question is, when will they be old enough to go back to the barn and not be bothered by the cold? Should I keep them in until they're 6 weeks? Any help from anyone who's ever been in a situation like this is much appreciated. BTW, we named them Daisy and Duke!
