I went out to check my Muscovy ducks eggs and there was a hole in the air cell side not from the duckling. it was big enough to see inside and the white membrane is stuck around the duck without a hole I can see. The duck is moving around the membrane. the last time I candled, a few days ago, I seen a shadow in all of the eggs but Still no pips. They should be hatching soon it's been the proper amount of time. What should I do? I don't have any type of camera to take pictures.
