This would indicate that the egg may also not have the nutrition it needs to grow into a healthy duckling.

One only needs to experience a rotten egg that has exploded once to appreciate the value in being able to see “inside” before hatch time. Originally, eggs were held up to the flame of a candle to see inside - probably because candles provide a nice, small, intense source of light.
