Pan Hsu-huang, 41, raises ducks on the Hengchun Peninsula. In the early days, he says, ducks were left to roam freely along the Ssuchung River. This spacious natural environment, the microorganisms and minerals that the ducks absorbed from the sand and small stones along the river, and the fiber they ingested from feeding on grass caused the yolks of their eggs to take on a full, reddish color.
現年 41 歲的鴨農潘旭煌表示，早期車城鄉養鴨人家，將鴨子野放到四重溪邊放養，鴨子在天然環境中，空間大運動量充足，加上從溪邊的細沙、小石子補充礦物質和微量元素，吃草補充纖維質，因此產出的蛋黃飽滿紅潤。
