My eggs are 55 days old today, ive had them at 84f so about the same as you. Its directly related to temperature, but even then theres no definates unfortunately. Im so impatient though, wish they would just hatch! Lol
you're generally looking at about 60+ days, you can cook them at a higher temp and you might reduce the incubation period by a day or two but risk creating corns with congenital defects so IMO it really isn't worth it for the sake of a couple of days
