My pygmy goat is pregnant and I'm not sure when she is due. She was already bred when I got her. But I've had her 4 months. Her udder doubled in size since yesterday and her ligaments are gone. With my other goats they had a mucus discharge for the few weeks prior to kidding but this one has had none at all and still doesn't . Just wondering if she could possibly lose mucus plug just before kidding or is something wrong?
