Help! Dog got ahold of a duck egg!
Type 'Assisted Hatching' in the search bar at the top of the page. Several pertinent threads will appear. Good luck.
If you start picking at the membrane and shell, stop immediately if any veining and blood appears. The problem lies in having the duckling hatch before absorbing the yolk. On the other hand, waiting too long is not good either. It's a fine line to be walked.
