So it is day 60... One of the eggs had rotted a few weeks ago and grew a lot of mold, which spread to two other eggs (that were likely already unhealthy) and seems to possibly have killed them, because they changed color and most of the veins disappeared... Two other eggs are still white with strong veins, but there's no signs of them leaving the eggs. I've already cut a small triangle flap.

They were incubated at a bad temp range for the first half of incubation, between 87-89. (It's a long story...)

About 3 weeks ago, I finally put them in an incubator that actually works properly and so they were incubated at exactly 88 for the remaining incubation period until now.

Anything I should do? What day should I wait until I do anything?
