Five salted duck eggs

I've always liked duck eggs since I was a kid, and my mother's hands were amazing, and whatever the food, they could be super delicious. I rarely make duck eggs, because fresh duck eggs are often not available, so they're usually bought at the supermarket, and they're sold out of the market, and they're oiled out, but the only thing is that the protein is too salty, it's almost impossible to eat directly, it's better to make other dishes, and it happens to be fresh duck eggs, and then they become duck eggs when they come home. The duck eggs made this time did not reach the point where they were fully oiled, because once they were taken out, they felt completely salty, and if they continued to bubble, they would be salty, and if they were to reach the point of full oil, they would continue to bubble. It's not full oil, but it tastes good, and the yolk is already sandy. Fish and bear palms cannot be taken together, either at home or outside, as if they were made or bought at the same time. Here, let me ask if there are formulas that allow the duck eggs to be fully oiled and not salty, so that they can eat the right taste, if you do。
