In response to animal welfare concerns, we are developing a technology to determine the sex of chickens at the pre-hatching stage. Based on the hypothesis that the direction of rotation in the oviduct differs between male and female chickens during egg-laying, we aim to distinguish between the sexes by analyzing the contour shapes of eggs captured as they are rotated in 90° increments. This report outlines the proposed method, discusses key considerations, and presents the results of our study. |
