I know how to vent sex, but with a bird this size, it does not sound like a fun venture, so I was hoping for an easier way. I had been told before that to sex a goose, you can just look at the undercarriage. A male has 2, um, lines or folds? (again, hard to explain!) and the female only has one. But this bird really does not have any yet. Belly looks most like my male ducks. Does not look heavy with eggs, but I do not know if geese tend to look that way like ducks do.
I get told that by lots of people that's how you do it, but they're totally wrong. The 'things' on the undercarriage are called "lobes". A good show goose will have two equally sized lobes. If they're uneven or only have one, then they'll be marked down in competition (if it matters).
The way I would tell what sex he/she is would be if you had a bunch of Tolouse, the females are smaller in comparison.
As far as vent sexing, it's the only way you can go. And it's far easier on geese since their anatomy is bigger. Actually, it's best to learn to vent sex on geese before moving onto smaller creatures.
Thank you! Great to know what lobes are, and that they cannot be used to determine sex. Guess if the goose stays for long, I'll go ahead and vent sex. I did not hear back again from the Craigslister, so maybe they just do not want it back? Who knows.
While I cannot say much for where this goose came from, it is currently anything but "alone", although is the only goose and will remain so while it is here. There are plenty of ducks and chickens here, and the goose seems to like my Pekin duck. I have 6 fenced acres, and 2 good dogs, and have never had predator problems.
Thank you for your help, I greatly appreciate it!
