There is a little more information here. Try candling after dark. Having a non-incubated egg handy for comparison is a good idea too. I still think you don't know what you are looking at but once you see it, you'll wonder how you missed it.
If you smelled the individual eggs and they smelled OK, they are not the problem. You would know if they were. Sure you did not step in something? You do have dogs and cats.
Them being sweaty when she gets off makes absolutely no sense to me. Since they are warmer than the air temperature, they should be dry. I'll keep my jokes to myself on this one. Seriously, I don't understand that.
