Day 14 candle of 9 buff orp eggs showed 9 perfect, on target babies. Moving and happy. Today is day 18, 8 look perfect, but one looks like it has a circle of nothing and it's crowded on one side of the shell. It's alive and moving. I am pretty sure one of these had two yolks, but as development continued, the "second" yolk disappeared, I assumed I was seeing things any idea of what this is and how much hope I should hold for this baby hatching?
