Abstract
THE purpose of the experiment reported herein was to determine if there were sexual differences in growth and in the utilization of feed in chicks. One of the great handicaps previously encountered in nutritional experiments with growing chicks has been the difficulty of adjustment of sexual differences in growth rate and feed efficiency where chicks of mixed sexes were used in the experiment. The weighing of the chicks individually has permitted the computation of sexual differences in growth, but it has been necessary to estimate the feed consumption and efficiency for males and females as the chicks were not segregated at the time of hatch.On April 11, 1934, a hundred day-old White Leghorn pullets and a hundred day-old White Leghorn cockerels were sexed and placed in separate compartments in electric battery brooders. Both the pullets and cockerels were fed the Washington chick starting mash: ground yellow corn 40, ground .
