I bought five ducks back in March and built them a little floating house. I kept them in a fenced in area until they were fully grown and now they live in the pond on my property but they are terrified of the water! They had a deep pool to swim in before but now they won't go any deeper then they can stand and they refuse to go into the duck house. Before I moved them to the pond they were trained to go into it at night but since I moved it into the pond they are terrified of that's too! What should I do? How can I train them to go in the house at night? Help!
