Fertile egg will look dark and near solid except air sack if candling at day 14 when you are removing the eggs from the egg turner and candling while placing into a lockdown hatcher. We recommend not candling until this day, so it is the only time you test and candle eggs. Testing too soon can lead to false readings.
