Reading the ligamentsA goat's rump is normally flat and solid, but as a doe gets to the end of pregnancy, that changes. Her tailbone becomes elevated, and the ligaments that connect it to her pelvis begin to stretch and loosen in preparation for the journey the kid (or kids) will make from her body. Sometimes you can tell that she will kid soon when you see a hollow on either side of the tail.
One of the best ways to identify an impending kidding is to feel the two tail ligaments located on each side of the tail. Feel a doe that isn't pregnant and you will notice that those ligaments are very firm. The same will be true of a doe that is pregnant but not ready to kid.
When these ligaments begin to get soft, and then completely vanish, you know that the goat is due to kid within 24 hours. You may make a mistake the first few times you try to read the ligaments, but over time you find the technique to be almost foolproof.
Identifying other signs of impending kiddingBesides softened ligaments, a doe will show other signs of kidding. Each doe might exhibit different signs, so keep an eye out for a change in behavior. Some other signs to look for include
Isolation: The doe stands off from the crowd, sometimes seeming "spaced out."
Mucus discharge: You may observe some whitish or yellowish discharge on her vulva.
Firm, shiny udder: Her udder may become tight and filled up, called bagging up.
Loss of appetite: She may become uninterested in food.
Personality change: She may start fighting with other goats or become overly friendly to you when she was previously standoffish.
Restlessness: She may lie down, then get up, paw at the ground, and just seem uncomfortable.
When you have determined to your satisfaction that this is the day, turn on the baby monitor and leave her to focus on the mysterious process of having a kid.
