85 is an okay temp. Depending on how long it has been since they are laid you can look at a incubation time of over 100 days. Tokays can take a long time which can sometimes drive keepers nuts. My wife was doubting one of our eggs was even fertile until at 115 days it finally hatched. Short of the egg being discolored and smelling it stays in the incubator until it hatches. Good luck with the eggs and keep us posted on them.
