I have a tough time getting my free-rangers into their house. They are in lock-down now - all except Milly Mallard that decided to hang with the chickens. I have noticed then when I do trap the ducks in their new house, they get very quiet - except when I talk to them - then they talk quietly back. Is it a good sign that they get quiet in their house? The first 2 nights they were in, I found Mallard eggs. I have found one in the yard, otherwise, it has been hit / miss getting these guys into the house at night.
