Do roosters reach food faster than hens when an obstacle stands in the way? You time how long it takes roosters and hens to reach a food tray placed four meters from their cage. You test two age groups: one-month-old and six-month-old birds. On the first day, the path is clear. On the second day, you place a three-meter log between the cage and the tray. This reveals how each group handles a physical barrier. Without the log, roosters and hens arrived at nearly the same time. With the log in place, roosters reached the food noticeably faster than hens.
