I have my seven two-week-old runners outside today. I sat in the grass and they played around my legs. They enjoyed nibbling the grass and my legs, and they knew to stay right by me. After a while, my drake and hen (they are the parents, but they don't know it) waddled by, and Dewey (the drake) was really interested in the ducklings. He kept circling me and checking them out. He didn't come close enough for me to touch (I have never been able to touch him....he was an adult when I got him and not socialized), but he was so curious. I would not have let him get any closer to the babies, because I was afraid he might hurt them. Is it possible his interest is not aggressive? Or is he scoping out the competition?
