I'll post this here for you Reenie in regards to your question about eggs being uncovered; this is from the San Francisco topic and was brought over here. It addresses concerns they have there as well and their response was:
Glenn S posted an interesting response on Yahoo forum last night regarding FC & Clara appearing to have started hard incubation:
"Long periods" do not equal "hard incubation." The parents have to bring the eggs and the surrounding area up to 99 degrees to start incubation. One of the things we have learned by watching these cams for years is that the adults "rake" gravel toward them until a donut us formed around the scrape. I am convinced that the donut, dike, or ridge, helps seal out the cold and helps maintain temperature for the eggs. The eggs are sitting on a substrate of cold gravel and I am saying that it takes significant effort to bring the gravel of the scrape up to a constant and warm temperature. Once incubation has begun the embryo starts to develop but that does not mean that the eggs must be covered every minute of every day to survive. Eggs are tough. They can go uncovered for an hour or more--and there are records of eggs being uncovered for significantly longer periods. There is some evidence that they begin to shut down when they feel two eggs under them (this is from captive situations when eggs are added to the nest) so they complete the clutch at 4. Think about it. We know that when egg #2 is laid, egg #3 is already on its way down, right? Egg #4 is about to be fertilized at the top of the infundibulum. So if the "shut-down" trigger comes after two eggs, we should get a total of four in the nest. --glenn@scpbrg
