One of my pygmies had twins 8 almost 9 weeks ago and then her sister had a single this past Friday night. Right now we have each of the "families" in their own pens and the rest of the goats have the remaining area as well as the barn. The "maternity" pens each have a house in them with straw and the newest baby has a heat lamp in it because our nights are still in the mid to high 30's. My question is when is it safe to have the babies turned out with the rest of the herd? I have a rescue female who is mean and chased and butted the babies when I tried to let them out a couple of weeks ago. This is my first experience so not sure what to do.
