Sexes

[Athiena14]

How can you tell sexes on mixed geese. I got 4 adults and the people didn't know what sexes they were. I'll take better pics in the morning. They are currently in my laundry room so excuse the dirty clothes pile.

One of them is part Sebastopol

I'm by far an expert yet, but what I've seen is males have longer necks, and are overall bigger. They also lack the lobe fat that females may have, or at least have less. They also have a distinct honk. My females talk a lot, but it's never an actual honk like the male does.

It’s hard to say, like @oldhenlikesdogs said ganders tend to have longer necks, they also tend to be more outspoken and louder, females tend to have a deeper voice and most of the time are more docile and wanting to stay behind the gander, most of the time, not always. Usually ganders are larger, but not always, if they’re mixed breeds it can get more confusing. As for everything else it varies by breed and by individual.
Lobes aren’t a good way to determine gender from what I’ve seen personally, I have a few ganders and girls with a single central lobe, but I have a few ganders and girls that are two lobbed, for example my Toulouse gander Leo is single lobbed, his son Parsnip is two lobbed. Sometimes goslings will be two lobbed when they’re under a year old but develop a unilobe after, lobes are pretty much fat reserves so I guess it must depend on how they’re genetically predisposed to carry their weight.

Sometimes color can help determine gender in auto sexing breeds, but if their parentage is unknown it can just make it more confusing. The sebbie mix looks like it has Buff coloring, female geese only need one copy of a gene to determine color, males need two copies, so the sebbie would need both parents to be buff or to be split for Buff to be Buff if it’s male, it only needs one copy of the Buff gene if it’s female, so my guess is the sebbie is female.

The one that’s mostly white kinda looks like a male, but it’s hard to say.
