I was wondering if anyone here uses mineral oil to coat their eggs before going into the incubator? I know this method is used for preserving eggs for up to a year for eating.. But I am curious if it helps the eggs or harms them when used for incubating? I have a friend who washes the bloom off all her eggs when she collects them, she then coats them in mineral oil because she says it helps the eggs incubate... So curious about this!?
