I've had chicken and ducks for years. I see them having sex all the time. I'm new to geese. I have a "mated " pair of african. They are at least 3 years old. I've had them for almost a year. They are never more than 2 feet apart from each other. But I have never seen them "do it". My concern is if her eggs will be fertile. Also how many will she lay before she sets? Thanks.
