INVESTIGATIONS ON THE NATURAL EGG LAYING HABITS OF DOMESTIC GEESE

Abstract

The present study was based on the examination of the natural egg laying habits of domestic geese. The authors studied Grey Landes geese during the summer laying period. On the day of arrival of the birds a TyniTalk II artificial egg was placed in each nest. These eggs contain a microchip which detects and records data on the temperature of the surroundings. The results obtained demonstrate that after laying a certain number of eggs females laying under natural conditions sit on the nest not only when laying new eggs, but also to warm the eggs in it. The time devoted to warming increases with the laying period.
