So, my incubator stopped working, and I've got 20 highly valuable eggs inside. Will they survive for a few days until a new one's delivered, or am I screwed
They will be fine, even at 70 F it wouldn't hurt them but put them in the warmest part of the house you can that's closer to 80. BTW, if you have room in your dragon's tank on the cool side [ anywhere up to 86 F ] and they could safely be placed in there that would also be an option.
