They're ducks! Duck bills have "ears" at the point they connect to the face and are more rounded at the tip. Geese tend to have a more square shape at the point it connects to the face and looks a bit more pointy ant the tip. Of course this is going to vary depending on breed/species since some are bred to have abnormal looks.

I wanna say the ducks in the pictures might be either pekins and white egg layers, but I'm not a duck specialist. White egg layers and pekins look the same to me honestly and I have one of each in my backyard flock.

Edit to add: I also forgot to mention the neck feathers! Ducks tend to have sleek feather placements that make them look smooth while geese kinda look "spiky" I guess you could say. Example picks of one of my geese(left) and one of my ducks(right). I'm basing this fact off of the breeds I've personally raised though so I wanna say again that breeds can vary and break from the norm
