I'm going to try this. So its circle for filly,back and forth for colt and no movement for not bred? How long after she is bred do you wait until you do this with the mare?
I did the nail test on two of my 3 expecting mares, both showed fillies. One mare has foaled now. . .a filly !!! I am doing the third mare this weekend. I have done this several years before and it was 100% correct. . .how and why. . .who knows. . just one of those strange happenings.
