Recognize the signs that your pregnant goat is about to give birth so you can be as prepared as possible. A goat's gestation period is between 145 and 155 days. If you have a pregnant goat, you should prepare a kidding stall for it to give birth in. Place the goat in the kidding stall at around 140 days of pregnancy. Fias Co Farm recommends staying with your goat while it gives birth, as you may need to assist if there are any problems. Have the phone number of a veterinarian you can call in case the goat requires medical assistance.
