Our ducks are 6 months old and laying lots of nice eggs. They are penned up at night and free range during the day. All of a sudden they will not go in their pool where they used to spend half there day. I have cleaned it and put lettuce and beans in it and still no luck. Maybe it is because the temperature dropped? I thought they would go in all year round. They wont even come near it where I usually hand feed them food. I have go to them now. Any thoughts out there? Also thought it might be the change in season with the time changing as well.
