I have some Black Swans, and we just moved to a 16 acre farm... but no pond yet. I built them a temporary 10 X 16 pond so they could swim and get some exercise... They do use it, but all my Black Swans seem to spend more time walking around then swimming.... always have. I always thought they spent more time in the water? All are pretty friendly, but one female who as a cygnet, was never thrilled with me and always ran, has now decided that the rather likes me. She tried building a nest on the porch on my backdoor mat, bit at the door and looked through it to see where I was, talked and honked into the glass.... She will follow me around and when she stops walking, she starts trying to build a nest. We ended up fencing off our backyard to keep all the animals, especially the cranes, from dragging out stuff, but now she stands there closest to the house, bites the wire and honks at me while I'm in the house or outside. I feel bad for her. She has 5 other swans out there with her, they have dog houses, hay, woods, and the temp pond....... She is already honking for me this morning, but it's too cold to go out yet.
