Lockdown is tomorrow so I need some quick information. I have the basic jist of how this works. . . cut the cups down and cut out the bottom for air flow. Leave a "dance floor" in the middle of the incubator. My questions are: 1) I am not planning to re-use cartons, should I use the cardboard or the styrofoam one? 2) Do they eggs stay large side up, or should they sit sideways. My chicks are at high risk for being stuck because my turner was not working for the first 10 days of the hatch. Thanks in advance for your advice.
