Chickens treated with allylestrenol or diethylstilbestrol in the egg on 9th day of incubation, or one day after hatching, or on both occasions, equally showed histomorphological indications of a distinct ovarian activation at 5 days of age, which was most pronounced in the twice-treated birds. A single steroid exposure at one day of age accounted for inhibition of ovarian activity at 6 weeks, presumably owing to a long-term effect on the hypothalamo-hypophyseal system, which begins to function from the 12th day of incubation.
