I grew up raising boar goats and the way we would check to see if they were close to kidding is to take your index finger and your middle finger and put them on each side of the goats tail and check to see how far apart they are we could usually get 2 finger widths on each side of the tail.
Also the way we would tell if they were preggo is to hold the tail up and feel the underside of the tail, if it is really soft and squishy they are preggo. You can tell a big difference if one that is preggo and one that isn't.
