I am currently incubating duck eggs and I went to do my final candle before preparing eggs for lock down and 2 eggs pipped into the air cell early(by 6 days!) One egg is peeping a little but made no further progress in 2 days. The second egg has started turning grey, almost like it was bruised! I panicked and broke rule number one of not candling after lockdown.(which I did immediately after I noticed them pipped into the air cell) and I candles the bruised egg breifly, and the aircelll is now partly full of yellow fluid! What happened?! Is the duckling still going to hatch? Should I do anything? This is my first time incubating duck eggs. These are the best pictures i could get of the bruised egg.
