Im not an expert on the issue but i have 4 sthenos and they have laid, the eggs were infertile anyway.
The one with the dent in it may be/become infertile or so ive read, Rolling of the egg isnt a major issue or atleast again so ive read elsewhere, Excessive rolling of an egg will ruin it.
If i were you id get 2 soda bottle caps and fill them with sand and place each egg on an individual sand filled lid and place that in a tub of moist soil/vermiculite/coco husk.
HOWEVER from looking id rather you just left them the way they are in the incubator for now, next set of eggs follow the instructions above, they are apparently best.
One is already minorly damaged but it shouldnt effect it too much.
Just monitor the humidity level of the Tub, watch the temps and wait and hopfully in around 70 - 80 days you should have 2 little steno's
and Whatever you do, DO NOT pick them up to candle.
In about a week or 2 the eggs should turn pinkish, it may not be noticeable at first but if you take a torch and shine it on the side of an egg and look at the other side(this is know as candling) you will see at first a pinkish/reddish blob or the entire egg will be pinkish/reddish, OR you will see pink/red with Veiny like things(usually later into incubation) this means they are fertile.
Either way wait till the incubation period is long over before thinking the eggs are duds.
Hope all goes well
