Aren't geese wonderful?! Lucy, Linus, Sabrina and Basil are best buddies as a group. There has never been any aggression between Linus and Basil, and they have never been aggressive towards us either. They do occasionally pull at the feathers of the swans who share the same area, and the swans get out of their way or ignore them. Linus is regarded as the main protector of the group and Basil is the dependable backup guy. Sabrina and Lucy laid some eggs their first breeding season and sat together as you can see in the photo, but their eggs disappeared - I'm not sure what happened. We shall see what happens this breeding season. They are starting to get more vocal, so I think their hormones are starting to kick in.
I feel just a bit envious when I see photos of your cuddly Sebastian, because the little gaggle won't let us hug them like when they were goslings, but they are still lots of fun.
