Abstract The development of peck orders in mixed sex groups of domestic chickens was observed to determine how linearity occurred. Based on threats, head-pecks and submission, dominance relationships emerged in a virtual peck right form. Leaping by males, however, did not closely conform to dominance relationships. There were no rank reversals in 50% of male-male and 80% of female-female relationships, and only single changes occurred in most of the others. These resulted from the movements of individuals up the hierarchy rather than from any general reorganization of relationships. Reversals did not necessarily occur between rank neighbours, and stable triangles were sometimes introduced. The initial status of males and females depended upon the age at which they first showed aggression, while the final, stable status of males depended upon the age at which they were first submitted to. Sexual maturity of the males produced a number of changes, with earlier-maturing birds tending to rise in status above their later-maturing companions. Linear hierarchies therefore appear to result from birds developing at different rates.
