It took 3 weeks, but I found out where the geese came from. They had been on the lake (we live a short distance downstream from a lake). On that lake is a campground owned by my next door neighbor's family. Neighbor's kids and uncle caught them, thought they were ducks, and because they were so tame, they thought they were ours and left them at our barn while we were away. Seems they were probably turned loose at the public access. I have been turning them loose and they stay very close to the barn area, and seem to like it here. They are tamer than the ducks!
