Because water poultry's egg(Duck,Goose and Muscovy)is larger;relative surface area is smiller;eggshell is thicker;membrane of eggshell is tough and tensile;the fat content of yolk is hight and embryon metabolizes vigorous in mid and end course.So the hatching factor of egg of water poultry is difference to hen's egg.This paper discusses the hatching factor of egg of water poultry temperature,relative humidity,venlilate,turn over egg and cold egg.
