They should be fine, only thing I'd be really concerned with is the lack of humidity. If the eggs are really on just plain paper towel with nothing else in the tub adding humidity they may start to dimple a bit by time you get back.
I also think the roll out egg should be ok unless its infertile to begin with, but I'd imagine it would also suffer from lack of humidity like the rest of the eggs might, on top of the fact that its not in moms coils.
