Well about 3-5 years ago my grandparents had about 8 geese. One was female and the rest were males. The female laid many eggs but they never hatched. Well one day a lone canadian duck arrived. This was durring the fall and probably it had lost its mate. It stayed all winter with the geese. In the spring the female laid here eggs. And guess what. We now had 3 baby canadian geese following an american goose. At the end of that year. The canadians took off. The american geese must have thought to follow and they took off as well. (only about 5 feet from the ground) The geese and the canadians were never seen again. I really miss gettign chased by the geese while stealing a egg.
