Can you tell from this picture if the 2 swans that displays their face are females or males. The middle swan has a bigger bulb and it's very aggressive and territorial. It acts like a male. Those 2 swans have a nest each year but they never hatch their eggs. My swan is the one on the far right that does not show its beak. The other two beat my swan up and I brought it home. We don't know how to tell what we have. My other email was a picture of my swan with a duck in the pond.
