It looks as though the egg in the first pic is getting to much moisture. Try using the light diffuser from a hardware store to elevate the eggs off the vermiculite. Then you will not have to worry about the eggs getting too wet.Second if you are getting condensation on the tub it means the air temp in the tub is different then the air temp in the incubator. You need to add more holes to the egg box, or increase your fan speed if you have a fan. If you do not have a fan it is really recommended. The egg with the dark window, I have seen this develope in eggs after about two weeks of incubation. It was not noticed when i put the eggs in at first, but i believe it is there and just gets darker as the eggs develope. It is not a problem as long as you have good veins, and the eggs are not rotting or collapsing alot then keep on incubating them they look fine to me. Just fix your water situation and the eggs will do fine.
