My geese which were bought as a sexed pair, my male is taller, has a longer neck, weighs more stands more up right and all. My female is the opposite but there is not a huge difference in overall size. My friend has embdens. His females are much smaller and much more petite. Boris is the same size as his male embdens. Natasha is much bigger than his females. I did not know if I just have a big girl or if his are small.
