A lot of people have a custom of boiling 3 eggs at a time, as mentioned here, among any other places.
One reason given for this practice is that if one egg turns out to be unkosher, the remaining two kosher eggs will be a majority against the prohibited taste, and they and the pot will remain kosher.
I do not understand this reasoning. If you boiled 3 eggs and cracked one open and found a neveila chicken inside, it is totally clear to me that everything would be prohibited. Kashrus 101: You need 60 parts kosher to nullify the 1 part unkosher! So what good does it do to have 3 eggs?
Is this practice really justifiable by that reason or not?
