Figure 1

The music notation graph for four hens on their first day of meeting. The horizontal lines represent the hens by their ranks within their hierarchy: red for the top-ranked hen, blue for the second-ranked, green for the third-ranked, and black for the fourth-ranked. Arrows indicate aggressive acts from one hen to another, and the arrows are in the color of the initiator and go from her line to the line of the receiver. The numbers at the ends of the lines show the wing badge identification numbers of the hens, and the time in minutes and hours elapsed since the group was introduced is indicated above each block of the graph.
