Hairline fracture- help

[Emma_Bruffy]

Today when I candled the eggs under my broody one of the eggs had a small hairline fracture at the point end. It goes from one side over the top and down the other but its altogether about 2 and a half inches long. I dont know if the membrane is intact but I have the crack sealed with wax and it's in my incubator what should I do? Will it be ok?

important details I left out- it is a chicken egg- its on day 7- I need to know the humidity and temp I should use, is it normal temps? - do I turn it as often as normal- will incubator type matter for its survival?
