Abstract

Cases of adult hens showing cock characters have been studied extensively, but doubling of structure is seldom found beyond the embryonic stages. This case of a White Leghorn hen is of interest not only in that she carried some cock characters while laying normal eggs, but also in that she possessed some marked anomalies that are indicative of irregular embryonic development. The Poultry Husbandry department, Iowa State College, gave this particular hen to the Genetics department in the spring of 1927. She had been sent to the college by an Iowa farmer some time previously. From Nov. 20, 1927, to March 5, 1928, she was kept in the Genetics animal laboratory with a flock of hens which were under regular laboratory observations. On March 5, 1928, the hen was photographed, dissections were made, and histological studies were begun.
