Q, We usually make kapparot with chickens. I have learned that if one's wife is pregnant, one should procure for her two chickens and one rooster, in case the baby is a boy or a girl. Can you rely on an ultrasound test and just bring a chicken for the mother and a rooster for the baby boy?
A. Contemporary Poskim differ, some maintain that one can rely on the ultrasound images for kappores purposes (Kone Bosem 2: 20 and others). Minchas Yitzchok disagrees.
A physician advised, that it depends on what gender the test shows.
Horav Shlomo Miller's Shlit'a opinion is that one may rely in our days on an ultrasound test for kappores purposes.
