Hey!! I'm new @ this. Our goat will be a first freshener, today was day 152. She is mostly Nubian. She had about tablespoon goop earlier and acting like she was stretching and her vulva was twitching?? So I put her in her kidding stall....6 hours later she seems normal? She has had an udder for a few weeks but does not feel sizably bigger yet. Were/ are these labor signs? If so, how long labor last generally??? Thank you!!
