We are incubating some duck eggs for our neighbors. This was the first duck to hatch in this batch and he was alone for the first night. If you have been around ducks...then you know that when they are little and alone they can make a lot of noise/peeps trying to call you back to them. Needless to say we had to do something quick. So we found a stuffed eagle and put him in with the duck. It worked...we did not hear another peep the rest of the night. When the other ducks were hatched, they would all huddle around the eagle and go to sleep.
