I actually have never had the screaming except when I tried the separate them by a fence but don't let them touch method. Momma screamed all week and ran every last bit of weight off and looked like an Auschwitz survivor. I have gone as far as sending mom out to a boarding stable for 1 month, she dries up and it's all over. No fuss, no muss, but I ALWAYS do it by the moon. I do put a kindly uncle or auntie or other babies in with the foal. I also do all the foals on the place at the same time whether it's 1 or 5, works the same.
