If they are still like this after a week is it safe to say their chances are good and everything can be left alone temp and humidity wise for the rest of the 50+ days?
Probably, but it's good to keep an eye on them. I check a couple times a week to make sure the humidity is good... just look for dimples to form, if so, they are too dry. Otherwise, you should be able to let them go.
(But keep in mind that stuff can always go wrong. I've got one female whose "good" eggs randomly "go bad" throughout the entire incubation period. Most of them hatch, but quite a few just "die and rot" for whatever reason.)
