Does anyone have experience setting turkey eggs and then adding chicken eggs seven days later in the same incubator to synchronize hatching? I've hatched chicken eggs before in an old galvanized round incubator without a turner. I just built a larger incubator which will have a roller style turner (still manual but I won't have to open the incubator-just push or pull a rod). This one has a window so I can set up a web cam to let my grandaughters and local 4-Hers watch the hatch. Right now I'm having trouble getting the humidity up and I have too much temperature difference from one side to the other. I'm hoping that a baffle in the airflow and some additional insulation might solve the problem. I used the wooden cabinet from an old black & white tv and didn't have enough insulation to line the entire box this past weekend but I turned it on anyway because I wanted to check my heating and air system.
