Abstract
A few races of domestic fowls, such as the Campines, have two kinds of males, one showing the ordinary cock-feathering, and the other the so called hen-feathering. Three young Campines of a hen-feathered strain were castrated, one before the adult feathers had appeared, one when they had begun to appear, and a third that was like the last but exceptional in certain respects. This bird will not be considered here. Both of the former birds developed cock-feathering after castration. It is evident that removal of the testes in this race produces the same effects as is produced in the hen feathered Sebrights, as reported three years ago before this Society.
