Many people like to eat duck eggs, so many people choose the place to raise ducks in the mountains in order to raise them and sell them. There is a young couple who are raising ducks in the mountains. But the two of them found that a lot of duck eggs were lost every day. In order to find out why, they used duck eggs as bait and found that mice and birds on the mountain would eat duck eggs.
So the young couple took the fact that mice can eat eggs to heart. They were all in the deep mountains, so they could reclaim land to raise more ducks and do more things they wanted to do, and they could also grow some vegetables. At this time, they thought of a clever plan. They put duck eggs in uncultivated land every day. When mice and birds come to eat duck eggs, they will loosen the soil. This will reduce their spending more time on land reclamation.
Besides mice and birds, they also found that weasels can eat duck eggs. They just want to eat all the mice around them through the weasel, so that they can live a peaceful life. So slowly the mice came less and less, and the weasels increased. We all know that weasels are very good at eating mice, and they can catch three or four hundred mice a year. The young couple can clean up all the mice by using the weasel's hand. Don't worry about rats often harassing them.
