I currently have 8 French Toulouse geese that I raised from goslings. All 9 of them ran together many months this summer (one of them was lost, I assume to a predator). Now the weather is getting cooler and one of the geese no longer runs with the other 7. She stays on our "local" pond and doesn't venture very far away while the others continue to roam the countryside and go to our neighbors pond for a swim always returning to our "home" pond in the evening.
I have checked out the lone goose. I can't see anything wrong, she is healthy, fat, waddles fine, etc. Was she kicked out of the group for some reason? I'm pretty sure she is a female but, what do I know as a newbie? Is it possible she laid some eggs somewhere?
