I just put my assorted Duck and Chicken eggs into the hatcher. I timed it so that they would all arrive about the same time. Duck eggs take longer to hatch. I still have my Pene eggs in the incubator. I'll let them hatch in there since it has the didgital thermostate and they are the more important eggs. I'll let you know how it goes with my peeps and quacks. I'm so tore up right now...can't wait.
