Hi there. We're new goat owners and we have a doe that seems to be having a difficult labor. She seems to be having contractions, but I can't see a baby goat or bag or anything. Instead, we see what looks like a wad if pink flesh. She pushes it out to something a little smaller than a tennis ball and when the contraction ends, it sucks back in. That can't be normal. What is it? Do I try to intervene?
