This too is Nature

With some young ducks, the first eggs they hatch aren't suitable for human consumption. The shell is missing, with only the leathery membrane holding the egg together. Nature has a purpose for this egg - it's job is to open the duck's vent for future successful laying. This may happen to successful layers, as well, when an accident occurs and the egg drops down without having gone through the shell creating process or when the duck is malnourished. Information on this below the cut.

But meanwhile, you have these "no shell" eggs, which are rather gross admittedly. The best way I can describe this is to think of a three day old latex balloon, then fill it with mineral oil.
