This sounded ridiculous when I heard of it, but I tried it on my 16 mares/ when I had them/ and it worked!!! watch the moon and watch the size of your mares bag, when there is a full moon she has a huge bag, when the moon goes to a dark moon her bag actually shrinks. well, when it comes time, watch for the dark moon and then wean the baby, she will be dried up in no time. it was amazing and I would have never believed it unless I did it and I did.
