I have read that you can help to determine what time of day a goat kidds. The literature stated that a goat won't kid on a full stomach. I haven't tried it yet, but you are supposed to pull their hay or grain so that they are on empty when it's time to pop. Mine have 900lbs of free choice hay in front of them. They typically kidd during the afternoon or 3am. It's worth a try if you have an appointment and won't be around during certain hours. But I would not try it just to try it.
