4 years ago I purchased 6 African Geese. It resulted in 2 ganders and 4 female geese. All was going well for a while. My ganders and females had paired off. Then disaster struck...Coyotes killed all but 1 gander and 2 geese. I came home from work to carnage all over my lawn and a coyote leaving the property. Aside from being very sad and thus putting up fencing so that I won't have anymore predator problems, my geese no longer mate. They don't even show any sign or interest. they walk around their enclosure together along with 6 ducks, but I never see them mating nor do I have any fertile eggs. Anyone have any suggestions? Are they too old? It doesn't seem like 4 years to a goose should be too old...Do they miss their old mates? should I buy some more to introduce to the flock? any suggestions greatly appreciated!
