I have eggs in my GQF 1502 Sportsman incubator and this weekend the temps are going to drop down into the low 20's here in Southeast Georgia. My incubator is in an unheated barn. I am wondering if I should wrap the incubator in some type of insulation or not? Would it be safe? Or should I just let the incubator try to keep the eggs around 99.5 as best it can? Hate to lose the eggs to the cold.
