Robin I leave the water dish in there before the eggs are laid. I know it probably doesn't help but in my mind I think it might raise the humidity in the cage just a little which will further help the eggs. Also I have had a lot of clutches and I have never seen one lay a egg in a water bowl if that helps. Most of the time they move the aspen out of the way and lay on the plastic. Let us know if they actually lay in the moss that you are putting in there for them.
