If your eggs are setting in vermiculite and there is to much moisture, the eggs will absorb it. This might be why they are not dimpling yet. Be patient....as they get closer to hatching the eggs will start to feel softer due to the higher rate of oxygen being absorbed into the egg, and if there are eggs stuck to each other they will be able to be easily separated. Once they reach the point of being able to be pulled apart with no effort they are within 3-5 days of hatching. It is important not to roll the egg if you separate them, just place the egg in the same position that it was. I use the "No Substrate" method to set up my egg trays, lots of people use this method with great success. This prevents the eggs from absorbing to much moisture that can put pressure on the developing embryo, in extreme cases this can cause spinal deformities (kinks) or even death. If you are able to see movement inside the egg when you candle it, then just be patient and after the first one pips if you want to pip the rest of them they should be fine. Hope this helps...
