I would not use an LG. I do however use a Hovabator with fan and it works very well. Do not use the water reservoir, but put a small amount in a plastic cup in the center.
I use a GQF sportsman 1202 with the ability to hold up to 36 Emu eggs right now..has autoturn and the auto humidity unit....it has kept my temp rock solid now, since I set the eggs...plenty of room for both incubating and hatching..seeing as I'll have a staggered emu hatch, this will be most beneficial. I don't think I'd rely on the LG for hatching Emu eggs...I don't think they'd even fit to be honest..but could be wrong.
