I am SO SORRY! Our incubator is set at 37.5 degrees celsius and we have very good results from that. I am not sure what the calculation is to turn this into Farenheit, but I do know that 100 farenheit is boiling point for water, so I think you may have cooked them! They should be at marginally below blood temperature for humans, which is 37.6 degrees celsius. Humidity levels are also key. A commercial incubator will have a water bowl, which you top up during the incubation period and then double in the last two days before hatching as too little humidity makes the shells and membranes too hard to crack for the tiny beaks. You have to manage this all yourself if they are incubated. Normally a broody hen will provide the right temperature for the eggs and her body moisture provides humidity. She will also help the egg to hatch, by pecking at the shell from outside when she feels movement.
Don't crucify yourself with blame. Just follow the instructions on the incubator and try again!
