I have been told and heard so many rumors - others are even saying it...... When a goose/gander has that double lobe/flap thing between it's legs some are saying "that's a female" and others say a male only has one flap/lobe.... My goose Nanna has the double flap and my ganders have the "keel" type with one flap. BUT!!! My female Embden only has 1 flap - figure that!! So I can't tell on my goslings that are old enough now - all have double flaps - could they all be females?? 8 months now. ANYONE HAVE ANY IDEAS IF THIS IS A LEGIT WAY TO SEX GEESE??
