I dont think you should put heatwire directly on styrofoam it will melt it sometimes.I dont think it would start a fire but eggs are pretty sensitive and i dont know if the fumes could harm the eggs.I think it would be better with a heat mat.I seen a heat wire melt through a peice of styrofoam.Just my 2 cents
some types of styrofoam, when burned, create cyanide fumes
