| Abstract: | Initial paired encounters between Ss were determined. After these had extinguished, Ss were simultaneously released in a coop. Social orders were observed after 3 weeks in the flock. Subsequently, paired encounters were repeated.In one of the three flocks observed the social structure failed to stabilize. In the other two flocks the repeat peck orders corresponded highly with the social orders, but neither agreed with the original peck order.It was suggested that factors emerging from the social context produced the differences between initial encounters and the social order. On the other hand, once a pair relationship was learned in the flock it usually carried over to subsequent paired encounters. |
