Then I figure the little fella on the left is your gander, and the right is the goose. Darker greys tend to be hens, lighter greys tend to be ganders, though there is variation. I'm only just now getting an eye for Toulouse goslings - it's much easier to tell on a breed like Embden or Sebastopol.
If they were dewlaps he'd probably be advertising that + charging you quite a bit, so they're likely production line, which are supposed to be sweet birds! Love how fat they are. Be sure to give them nonmedicated starter feed, and make sure they get their B vitamins.
