1, first of all, pickled eggs or duck eggs are generally between a week to a month and a half, a long time the egg is not much nutrition. If you are afraid that the pickled eggs are too salty, you can fish out and wash and cook them, then dry them, and then put them into the brine, so that they can be kept for 6 months are fine, and the brine will not continue to soak into the eggs.
2, if your eggs are already very salty, fish out and wash and put in the water to soak for a few hours (the length of time depending on the salinity of your own eggs), and then cook, salty will be much less.
