My father has approximately 16 ducks that he has been in the routine of taking care of. Every morning he would go to the house that he built and let the ducks out to roam during the day inside a fenced in area, or pen. At night he would approach the pen, clap his hands twice and the ducks would file back into the house. Last week a hawk attacked and killed the male leader and now the ducks are lost. In the mornings they will not come out of the house and he has started feeding them inside the house. He said they are drinking well. The females have stopped laying. When they do come out of the house they huddle in the corner of the pen and anytime they are approached they will all scatter in different directions. My father is lost and needs to know if the ducks will ever get over the loss of their leader and return to the routine that he has had for years.
