108 is very high, 1st off how long was it that high or can you tell ??. What type of incubator is it, this will tell you allot. If they were at that temp for several hrs then I would guess no chance for hatch, some will tell you to keep them till hatch date has passed and that's fine if they don't rott first. Do you know your thermometer is accurate ??. What day were they on and do you know they are fertile ??
