I have a few ND does and have been through one kidding season with them. Last year, our goats labored for hours, but when they started pushing, babies arrived fairly quickly- maybe 10 minutes or so. When I attended two births at a friend's farm this week her ND does pushed for a long time- the second one was pushing (making slow progress) for an hour. I felt we needed to assist her when I saw that the baby nose/mouth was purple (lack of oxygen) and the doe was exhausted, progress was slow, etc. Luckily, the position was correct, so it was just a matter of pulling the legs on her next push. I think I did the right thing- everybody is doing well and we continued to support her with supplements during labor. Wondering what other people's time frames are usually for pushing, how long once the nose is out, etc. The 2nd kidding season at our farm begins in a couple of weeks! Thanks!
