egg incubator humidity dropped for 24 hours are eggs viable?

[SarahMay]

I forgot to refill the water for the humidity, but they were in a very humid room and it was a rainy day. The water was probably out for almost 24 hours, maybe less. Would they still be considered viable or dead? This is day 5 or 6.
Also, I am only flipped the eggs upside down every 2 days when I add water, should this be enough?

A lot of people that incubate do not use any water at all for the first 18 days (for chickens) called "dry incubation"--Just according to your humidity. Now lets talk about turning----you flip the egg from top to bottom?? Every where you read says the small end goes down? You been doing this/hatching a long time flipping them like that? You having a good hatch rate?
