Lian Manman specifically chose a piece of vacant land to build a duck house and assigned two people to help Da Gui and his wife. These Hepu ducks are precious ducks. Firstly, the duck house must be kept clean and cleaned several times a day, not unlike a human's dwelling. Lian Manman even went to seek out Wang Youheng for a herbal prescription that can roughly serve as a disinfectant. All this is to ensure the ducklings grow healthier and to prevent epidemics and diseases.
Furthermore, the feed for the ducklings is different from the regular duck breeding.
Lian Manman wants to breed foie gras, but after the ducklings hatch, for the first forty-five days, they are still to be raised on better feed and more delicate nurturing, compared to ordinary ducks. It's only after these forty-five days that force-feeding can begin. This is according to the data in her memory, and she also consulted with Lady Zhang and Da Gui and his wife's opinions.
