The eggs would be up closer to the heat----in a still air that could be a problem. If I remember correctly the thermostat is in the top middle which could get in the way. If it were "I"----I would shape/cut some 2x4" wire---space it up where the wire is close to the middle of the eggs---then you can open the incubator---pull/push the wire which will cause the eggs to roll some---all at one time. Good Luck!Sorry I wasn't clear, the egg turner is 15x15"; I can't get to the incubator at the moment to measure it unfortunately, bug I would estimate it's about 25" diameter, but the height change for the eggs might be an issue? Is anyone here familiar with this model incubator? It's quite old, but I have seen some threads about it on BYC.
