I just had my first set of eggs that I did expect and was prepared for. Then she popped out 2 more eggs way quicker than I thought she would and was in the same boat you are in with the 2nd pair. By the time I found the 2nd set they were dented in and dehydrated like you explained.
After doing some research I found the eggs may still be good and should be given a chance. I read multiple places even experienced breeders have thrown away eggs thinking they were bad and found live babies in their thrash. There is different methods to saving dry eggs the one I went with was: To bury the eggs 1/2 inch below your medium (perlite, sphagnum moss, eco earth) in a deli cup and spray the medium so the eggs can soak it up. Do not get water directly on the eggs. Then incubate the dish as you would normally and check on the eggs every day or every other day. If they get moldy and smelly you know they are bad and there is no saving them.
For incubation I am using a Chinese food container with eco earth in it, placed on the hot side of my females 20 gallon. Before she had her 1st set of eggs I meticulously monitored the temps in the incubator dish finding the perfect placement in the tank for the right temps (I'm aiming for 80-85 F)
The 1st set of eggs that I was prepared for are doing great and should hatch sometime in the next week I believe. The 2nd set that was dehydrated are still kind of dented in, they are noticeably better and have no mold or bad smell yet. I'm hoping they stay this way.
I am in no way saying doing this going to help you. Research incubation methods without an incubator and ways to re-hydrate eggs and find what works best for you.
Good luck to you and your eggs!
