Hello everyone I am looking to purchase an incubator to hatch duck eggs. I've never done this before and I have a few questions before I purchase one. Do I need a circulated or still air incubator? Do I need a automatic egg turner? What all exactly do I need as far as thermometers and all..and what kind do I need? What does "lock down" mean? How long do they stay in the incubator after hatching before moving them to a nest with a heat lamp? (They will be inside my house in a large storage container with a heat lamp) Sorry for all the questions!
