As soon as pedigreed chicks break their shell they are banded on the wing and given a number

Life begins: Baby chicks see the first light of day as they are hatched from the pedigreed eggs, 1/19/38

Dr. Charles W. Knox, senior poultry geneticist, inspects the newly hatched chicks preparatory to banding them, 1/19/38

George Attick, junior poultry aide, removes the hen and eggs from the trap nest. The eggs are then marked to correspond with the number on the leg band of the hen. From here on the egg is checked through until the hen or rooster is full grown, 1/19/38

Shepherd Haynes, chief scientific aide, then places the eggs in an automatic incubator for a period of seven days, 1/19/38

Removed again from the incubator the eggs are put in individual wire baskets and placed in the hatcher by Mr. Haynes, 1/19/38

Superior chickens set. After removal from the incubator the eggs are put through the candling test by Mr. Haynes. Those infertile are given to charity while the fertile ones follow through the scientific routine with an additional ten days in the incubator, 1/19/38

The hens are then allowed to choose their own trap nests in which to lay the hens, 1/19/38

Superior chickens set. Douglas Grinnan, scientific aide, assisted by Benjamin Nehr, is shown fertilizing a hen to begin the experiments, 1/19/38
