The idea that a female duck can somehow control the fertilization of eggs based on her preferences or experiences with a male is not supported by scientific evidence. In birds, including ducks, the process of fertilization occurs internally, and once sperm is transferred to the female's reproductive tract, the female's body does not have a mechanism to selectively control fertilization based on her preferences.
