The film shows in detail the emergence of a duckling. At first the egg is only pecked at one point. After a pause a larger opening is made neighbouring this. From these the formation of a break takes place around the blunt end of the egg. The activity of the beak with the egg tooth point can be observed hereby. After the cap has been pushed off like a lid, the duckling, obviously exhausted, and with short pauses to draw breath, forces its way out of the shell. At first the down feathers resemble thick bristles and tufts but they fluff out after drying. Finally the allantois is also shown as foetal lungs and bladder and the umbilical cord through which only a few hours before hatching the yolk sac with around one third of the original yolk mass is drawn in.
