Hi I have 2 ducks that are almost 4 months old. 1 is a white female named Daisy and a male mallard duck named Donald. My question is why is the male not letting Daisy swim in the pool with him? If she tries to he bites her neck and pecks at her. The few times he lets her, he gets on top of her like hes trying to mate. I even put another pool for her to get in and he still wont let her get in any of the two. Any help is greatly appreciated
