Been trying very unsuccessfully to get my two 4 month old Swedish and Cayuga Drakes to swim in my pond in my yard. This a 1/4 acre pond that is about 6 feet deep in the center. After weeks of struggling and on the verge of living with Land Ducks, the boys felt a stirring in their loins. On Saturday a young Female Mallard showed up in our pond. The boys swam out to meet their new girlfriend, and now they quack like crazy trying to get out of their night pen so they can swim with their girl! Now without any coaxing they head to the waters edge and jump right in. The three of them swim around all day. After I eat dinner I head down to the pond and corral them back into their night pen, while their Girl looks on in disbelief as they waddle on home.
