Effects of External Stimulation on Embryonic Activity, Rate of Development and Time of Hatchingure (see Chapters 1 and 3). The embryo is active during the greater part of the incubation period, and although this activity is largely ‘spontaneous’, the embryo also interacts with its parents during the later, prehatching period. Interactions affecting motility, and based on vocalizations have be

The Nervous Systemwl embryo is given by Hamilton (1952). A day-by-day account of the morphological development of the domestic fowl brain has been given by Rogers (1960) and is summarized by Pearson (1972). Pearson (1972 after Krabbe, 1952, 1956, 1959) considers also brain development in the ostrich, kiwi and a numbe
